1 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
4 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
5 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
6 substitution will still be done by the special code.
7 Report by Jim Meyering.
9 * doc/autoconf.texi (File System Conventions): Mention that
10 $PATH_SEPARATOR is for the build system only.
11 Report by Keith Marshall.
13 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
15 * doc/autoconf.texi (Setting Output Variables): Mention that
16 all non-NUL characters are ok in substituted values.
17 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
18 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
19 carriage return for $AWK, needed for BSD awk.
20 * tests/torture.at (Substitute and define special characters):
21 Test all 8 bit non-NUL characters.
22 Report against Automake by Patrick Welche.
24 2007-01-15 Stepan Kasal <kasal@ucw.cz>
26 * doc/autoconf.texi (Specifying Names): `--host' does not
27 change the build type.
29 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
31 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
32 early on the reader side, drop stderr of the input to avoid
33 `broken pipe' error output; this may happen even with shell
34 builtin `echo' of some bash versions. Reports by Ian Macdonald
35 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
37 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
39 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
40 separate items of `ac_user_opts', to avoid long lines.
41 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
43 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
45 * doc/autoconf.texi: Fix some typos.
47 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
49 Fix some wording problems noted by Paolo Bonzini in:
50 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
51 * doc/autoconf.texi (Signed Overflow Examples): Give more
52 discussion about the allow_superuser_privileges example,
53 and change it a bit to make things clearer.
54 (Optimization and Wraparound): Clarify whether the compiler
55 will generate an infinite loop for the example derived from
56 Autoconf's mktime test.
57 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
58 Also, clarify unsigned multiplication overflow.
60 2007-01-04 Eric Blake <ebb9@byu.net>
62 * bin/Makefile.am (RELEASE_YEAR): New macro.
63 (edit): Use it to supply correct copyright year to scripts.
64 * bin/autoconf.as (version): Use it.
65 * bin/autoheader.in ($version): Likewise.
66 * bin/autom4te.in ($version): Likewise.
67 * bin/autoreconf.in ($version): Likewise.
68 * bin/autoscan.in ($version): Likewise.
69 * bin/autoupdate.in ($version): Likewise.
70 * bin/ifnames.in ($version): Likewise.
72 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
74 * doc/autoconf.texi (Integer Overflow): Revised based on today's
75 feedback. The most important changes document what happens when
76 you convert an out-of-range value to a signed integer type, and
77 say that (sum < a) != (b < 0) reliably detects overflow when sum =
78 a + b.
80 * doc/autoconf.texi (Integer Overflow): Greatly expand and
81 rewrite, taking notions from the recent discussion on the gcc and
82 autoconf mailing lists; please see
83 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
84 and follow the many links.
85 (Integer Overflow Basics, Signed Overflow Examples):
86 (Optimization and Wraparound, Signed Overflow Advice):
87 (Signed Integer Division): New sections.
89 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
91 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
92 preprocessor macro arguments in traced name.
93 * doc/autoconf.texi (Defining symbols): Document longstanding
94 support for AC_DEFINE-ing macros with arguments, and document
95 behavior when the same variable has multiple AC_DEFINEs.
96 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
97 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
98 macros directly, giving much shorter and simpler code.
100 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
102 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
103 space before "$ac_configure_args" to prevent a 'config.status
104 --recheck' failure if ac_configure_args doesn't contain a leading
105 space. This works around a problem with the XEmacs configure.ac,
106 which uses the (undocumented) ac_configure_args variable
107 inconsistently with Autoconf.
109 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
111 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
112 Include <limits.h>, and use its INT_MAX to rewrite the
113 j loop so that it does not overflow 'int'. Problem reported by
114 Ralf Wildenhues in
115 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
116 Play it safe by shifting left by 1 rather than multiplying by 2,
117 as GCC is less likely to optimize this away when the value
118 is signed (when it assumes overflow leads to undefined behavior).
119 Also, don't assume time_t uses two's complement.
121 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
123 * tests/torture.at (Substitute a 2000-byte string): Avoid using
124 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
125 dumps core on it. Report by Tim Rice.
127 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
129 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
130 --disable-option-checking to --help output even when
131 AC_PRESERVE_HELP_ORDER is not used.
132 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
133 --with argument, rather than argument with [-.] replaced by
134 underscores.
135 * NEWS: Fix typo in previous change; the news was in the
136 wrong section.
138 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
140 * NEWS: Warnings are now generated by default for unknown
141 --enable-* and --with-* options.
142 * doc/autoconf.texi (Option Checking): Renamed from
143 (Configure Option Checking). Tighten up the wording a bit.
144 (External Software, Package Options): Cross-reference to Option
145 Checking, and use this to shorten our section.
146 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
147 "$x" to test "x$foo" != x.
148 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
149 Don't warn if $enable_option_checking is "no".
150 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
151 ac_unrecognized_opts to the empty string.
152 Don't echo the unrecognized opts, as this might mishandle
153 backslashes or leading -.
154 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
155 usage next to the other --disable-FEATURE options in the
156 help string.
158 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
160 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
161 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
162 Print warning for unrecognized --with and --enable options
163 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
164 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
165 Disable option checking when subdirs are configured.
166 (AC_OUTPUT): If warnings are enabled, print warning about
167 unrecognized --with and --enable options at the end of
168 the configure output (as well as at the beginning).
169 * doc/autoconf.texi (Option Checking): New node.
170 Document new option warning functionality.
172 2006-12-16 Eric Blake <ebb9@byu.net>
174 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
175 * NEWS: Start news for current version.
177 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
179 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
180 Define HAVE_GETMNTENT to 1, not to the empty string.
181 Problem originally reported by Jochen Friedrich in
182 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
184 This change prompted by a problem report by Andrey Simonenko in
185 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
186 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
187 object-like macros only, in the traditional portable character
188 set.
189 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
190 Warn about attempts to define things that are not identifiers.
191 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
192 awful hack that AC_DEFINEd macro names containing parentheses.
194 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
196 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
197 too drastic, even if Texinfo in theory requires it for info mode.
199 (config.status Invocation): Renamed back from Recreating a
200 Configuration).
201 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
202 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
204 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
206 * NEWS: Version 2.61a.
208 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
209 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
211 * NEWS: Document changes with echo and printf, and the lack
212 of limits on the total size of multi-line values of substituted
213 variables, and the AC_FUNC_FSEEKO fix.
215 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
217 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
218 Writing configure.ac.
219 (Autoconf Input Layout): Renamed from configure.ac Layout.
220 (Recreating a Configuration): Renamed from config.status Invocation.
221 (Obsolete Recreation): Renamed from Obsolete config.status Use.
222 (acconfig Header): Renamed from acconfig.h.
223 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
224 (Writing Testsuites): Renamed from Writing testsuite.at.
225 (Autom4te Cache): Renamed from autom4te.cache.
227 * BUGS: Remove mention of VPATH problem, since it's now documented
228 not to be a bug in the Autoconf build procedure itself, but rather
229 a problem with the proprietary `make' programs.
231 * doc/autoconf.texi (Build Directories): Add a cross reference
232 to VPATH and Make.
234 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
235 * doc/standards.texi: Sync from gnulib.
237 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
238 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
239 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
240 generated automatically.
242 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
244 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
245 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
246 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
248 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
250 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
251 `CEOF$ac_eof' special marker, the awk script cannot contain a
252 line matching `^CEOF', so this is not needed any more.
253 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
254 special marker in the test.
256 2006-12-06 Stepan Kasal <kasal@ucw.cz>
258 * tests/tools.at (autom4te preselections): Use `find -newer';
259 remove one of the sleeps.
261 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
262 more readable, using ...
263 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
265 * doc/autoconf.texi (autoheader Invocation): Do not double-
266 quote the parameter of `AH_BOTTOM' in the example.
268 2006-12-05 Stepan Kasal <kasal@ucw.cz>
270 * doc/autoconf.texi (Configuration Headers): Remove the
271 example with multiple input files.
272 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
273 multiple input files.
275 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
277 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
278 creating the awk substitution script, handle one input line at a
279 time, so that the maximum length of a substituted (multi-line)
280 value is not limited by the size of the sed pattern space.
281 The trade-off is a slightly repetitive sed script.
282 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
283 can only have up to 7 characters, due to Solaris 10 /bin/sed.
284 * tests/torture.at (Substitute a 2000-byte string): Increase the
285 test with several long lines, they should not be caught by sed
286 limits any more.
288 * tests/tools.at (autom4te preselections): New test, to flag
289 entries missing from autom4te.cfg.
290 Report by David Byron <dbyron@hheld.com>.
292 * tests/torture.at (Substitute a 2000-byte string): Actually use
293 AC_PROG_AWK, so the last change works as intended.
294 (Substitute and define special characters): Likewise.
295 (Substitute a newline): Likewise.
297 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
298 instead of `awk' consistently.
299 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
300 * tests/torture.at (Torturing config.status): Test both the
301 result of AC_PROG_AWK and plain awk.
302 (Substitute a 2000-byte string): Likewise.
303 (Substitute and define special characters): Likewise.
304 (Substitute a newline): Likewise.
306 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
308 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
309 can be assigned to a function pointer. Problem reported by
310 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
311 part of a patch by Ralf Wildenhues in that same bug report.
313 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
315 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
316 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
318 2006-12-01 Eric Blake <ebb9@byu.net>
320 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
321 cross-compiling from cygwin to mingw.
322 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
323 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
324 to lib/autoconf/c.m4.
326 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
328 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
329 string for more reliable failure. Wrap the entire test that
330 causes the broken Solaris printf to dump core, in a subshell,
331 so the segmentation fault message is reliably suppressed.
332 Fix shell expansion errors by using /usr/ucb/echo always;
333 avoid an error on systems without it by another subshell.
334 Avoid m4 expansion of `$1'. Set the zeroth argument of the
335 subshell-$as_echo to `as_echo', for better error message.
337 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
339 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
340 `BASH_SOURCE' contain a newline, set them to empty, as they may
341 not be unset.
343 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
345 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
346 years and is too hard to maintain now. The last straw was
347 reported by Jerker Baeck in
348 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
349 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
350 * doc/autoconf.texi (Particular Functions): Move
351 AC_FUNC_SETVBUF_REVERSED from here...
352 (Obsolete Macros): ... to here. Say that it does nothing now.
353 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
354 Turn into (almost) a no-op.
356 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
357 (AC_C_VOLATILE):
358 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
359 These macros are obsolescent and new applications shouldn't need them.
360 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
361 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
362 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
363 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
364 (AC_FUNC_VPRINTF): Likewise.
365 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
366 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
367 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
369 * doc/autoconf.texi (Setting Output Variables): Mention that
370 @VAR1@VAR2 has unspecified behavior. Problem reported by
371 Ralf Wildenhues.
372 * NEWS: Mention this.
374 * Makefile.am: Put only a single '#' into the copyright notice,
375 so that it's also present in the output file. Standardize wording
376 in makefile copyright notices to match GNU coding standards.
377 * bin/Makefile.am: Likewise.
378 * doc/Makefile.am: Likewise.
379 * lib/Makefile.am: Likewise.
380 * lib/freeze.mk: Likewise.
381 * lib/autoconf/Makefile.am: Likewise.
382 * lib/autoscan/Makefile.am: Likewise.
383 * lib/autotest/Makefile.am: Likewise.
384 * lib/m4sugar/Makefile.am: Likewise.
385 * man/Makefile.am: Likewise.
386 * tests/Makefile.am: Likewise.
387 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
388 one-line file.
390 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
392 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
393 in the sed script that mangles the awk script: delete up to the
394 first exclamation mark only.
395 * tests/torture.at (Substitute and define special characters):
396 Test '!' too.
398 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
400 Rewrite config files generation: avoid quadratic growth in
401 the number of substituted variables by using awk instead of sed
402 for the bulk of the substitutions.
403 * NEWS: Mention this.
404 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
405 forbidden in the output (and thus input) file.
406 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
407 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
408 generate just one large awk script for substitutions,
409 eliminating much of the earlier complexity, while adding some
410 new complexity. Only expand the substitution templates at
411 configure time, for smaller configure script size. If
412 _AC_SUBST_FILES are used, test 'awk' for working getline support
413 at config.status time. If absent, interpolate through the
414 shell. The awk script was written with much help
415 from Paolo Bonzini and Paul Eggert.
416 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
417 (_AC_SED_FRAG_NUM): Likewise.
418 (_AC_SUBST_CMDS): Renamed from...
419 (_AC_SED_CMDS): ...this.
420 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
421 * tests/torture.at (Substitute a 2000-byte string): Also
422 substitute a line with 1000 words, and a variable with several
423 long lines.
424 (Substitute and define special characters): Test awk special
425 characters, and put substitution input strings `@foo@' in the
426 output, to test that no recursion happens; test several other
427 combinations from Paolo Bonzini.
429 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
431 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
432 that replaced echo with AS_ECHO where this wasn't necessary.
433 Problem reportd by Ralf Wildenhues.
434 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
435 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
436 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
438 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
440 * lib/freeze.mk (GREP): Removed, no need to initialize this.
442 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
444 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
445 that traditional Awk lacks 3-arg "split". It has it.
446 Mention that FS must be a single character, and a few other
447 99-byte limits of traditional Awk.
448 Mention that if (i in a) doesn't work with traditional Awk.
450 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
452 * tests/autotest.at (BSx641-newline in command):
453 (BS-BS-newline in command, BSx640-newline in command):
454 (Newline-CODE-BS-newline in command):
455 (Single-quote-BS-newline in command):
456 (Single-quote-newline-BS-newline in command):
457 Use printf '%s\n' instead of echo, for portability to hosts
458 where echo interprets backslashes. This will break on hosts
459 that lack printf, but for now let's assume all such hosts
460 are dead (if not, we should get reports of test failures).
462 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
464 'echo' has some portability problems, when given a first argument
465 with a leading '-', or when given any argument containing '\'.
466 Avoid using 'echo' in these cases.
467 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

491 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.

494 * lib/autotest/general.m4 (AT_INIT): Likewise.
495 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

511 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
512 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

519 * configure.ac (AC_INIT): Bump to 2.61a.
520 * NEWS: Likewise.
522 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>

527 * NEWS: Likewise.

589 no further ado.
591 2006-11-05 Karl Berry <karl@gnu.org>
593 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

611 non-working g++ installation.
613 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
614 and Joel E. Denny <jdenny@ces.clemson.edu>
615 and Paul Eggert <eggert@cs.ucla.edu>
617 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
618 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
619 ./micro-suite.
621 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
623 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
624 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
625 Imported from a similar patch to gnulib by Bruno Haible.
627 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
629 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

642 * tests/torture.at (Configuring subdirectories): Do not skip
643 Automake 1.10 nor future Automake 11.1 (sic).
645 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
646 and Stepan Kasal <kasal@ucw.cz>
648 Handle special characters in test case titles correctly.
649 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
650 properly.
651 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
652 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
653 argument. Extend to check titles printed by ./micro-suite and
654 ./micro-suite -l and the title in micro-suite.log.
655 (Backquote in a test title,
656 Single-quote in a test title,
657 Double-quote in a test title): Don't expect failure anymore.
658 (Backslash in a test title): Put a non-whitespace character after the
659 backslash so that Bourne shells might actually see it as an escape
660 sequence.
661 (Brackets in a test title,
662 Pound in a test title,
663 Comma in a test title,
664 Quoted Macro in a test title,
665 Macro in a test title,
666 Macro with single-quote in a test title): New tests.
667 (Macro with backquote in a test title,
668 Macro with double-quote in a test title,
669 Macro with backslash in a test title): New tests expected to fail.
670 * tests/torture.at (#define header templates): M4-quote this title in
671 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
672 The visible effect was a stray [] in the testsuite output.
674 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
676 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
677 `trap ... 0' inside a function, for AIX sh.
679 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
681 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
682 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
683 5363) simply issues a warning when dividing by zero at compile
684 time. Problem reported by Elias Pipping.
686 2006-10-26 Eric Blake <ebb9@byu.net>
688 * THANKS: Update.
689 * doc/autoconf.texi (Evaluation Macros): Improve the example to
690 show effect on macros that expand with commas.
691 Reported by Joel E. Denny.

698 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
699 Jim Meyering.

711 2006-10-24 Stepan Kasal <kasal@ucw.cz>
713 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
715 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
717 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
718 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
719 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
720 reported by Nelson H. F. Beebe for Coreutils 6.4.
722 * tests/tools.at (autoconf --trace: user macros): Remove test
723 for tracing multiline macros, since m4 1.4.7a uses a different
724 way to number lines. Problem reported by Ralf Wildenhues.
726 2006-10-24 Stepan Kasal <kasal@ucw.cz>
728 * bin/autom4te.in (handle_m4): Do not redirect stdin to
729 /dev/null since the heuristics for interactive behaviour was
730 fixed in CVS m4.
732 * bin/autom4te.in: With --force, always refresh the output
733 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
735 * bin/autoconf.as: Fix the verbose message at the end.
737 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

748 * build-aux/texinfo.tex: automake 1.10
750 * NEWS: Remove AC_CACHE_CHECK_INT.
751 * doc/autoconf.texi (Caching Results): Likewise.
752 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
753 AC_CACHE_CHECK_INT, since it's no longer public.
754 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
755 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
757 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

764 (m4_maketemp): Avoid warnings with M4 1.9a.
765 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
766 m4_mkstemp.
767 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
768 * NEWS: Likewise.
770 2006-10-16 Eric Blake <ebb9@byu.net>
772 * doc/autoconf.texi (Setting Output Variables): Fix typo.
774 * bin/autoconf.as (version): Reword to match GNU Coding
775 Standards.
776 * bin/autoheader.in (version): Likewise.

783 2006-10-14 Stepan Kasal <kasal@ucw.cz>
785 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
786 looking for special shell characters.
787 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
788 macro defined by AS_VAR_PUSHDEF before passing it as a
789 parameter.
790 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
791 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

796 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
797 AS_VAR_* properly.
798 * tests/m4sh.at (AS_LITERAL_IF): New test.
800 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
802 (Imported from Automake.)
803 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
804 which incorrectly sets the mode of an existing destination
805 directory. In some cases the unpatched install-sh could do the
806 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
807 system. We hope this is rare in practice, but it's clearly worth
808 fixing. Problem reported by Alex Unleashed in
809 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
810 Also, don't bother to check for -m bugs unless we're using -m;
811 suggested by Stepan Kasal.
813 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
815 Import this change from Automake:
817 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

819 is enabled by default with gnu and gnits strictness.
820 Report from Bruno Haible.
822 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
823 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
824 gnu and gnits modes.
826 Import this change from Config:
828 2006-09-20 Ben Elliston <bje@gnu.org>
829 * build-aux/config.sub (score, score-*): New.
831 Import this change from Gnulib:
833 2006-09-16 Karl Berry <karl@gnu.org>
834 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
835 to avoid sectioning errors.
837 Import these changes from Texinfo:
839 2006-10-04 Karl Berry <karl@gnu.org>
840 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
841 (\quoteexpand): rename to \rquoteexpand.
842 (\codequoteleft): new def, to look for @set codequotebacktick.
843 (\lquoteexpand, \quoteexpand): new defs.
844 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
845 (\code): must use new \...Char values, since now ` is active.
847 2006-08-26 Karl Berry <karl@gnu.org>
848 * build-aux/texinfo.tex (\textdegree): New command.
850 2006-08-12 Karl Berry <karl@gnu.org>
851 * build-aux/texinfo.tex (error \box0): smaller font.
853 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
855 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
857 2006-10-13 Stepan Kasal <kasal@ucw.cz>
859 * doc/autoconf.texi (Autoheader Macros): Warn that the text
860 added to the template can get mangled.
862 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
864 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
865 include the default headers, and redefine obstack_chunk_alloc
866 and obstack_chunk_free. Fixes false failure with glibc.
868 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
870 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
871 for backward compatibility with Libtool 1.5.22. Problem reported
872 by Ralf Wildenhues.
874 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
876 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
877 AC_PROG_CC.
878 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
880 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
882 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
883 the NonStop platform.
884 * doc/autoconf.texi (Posix Variants): Likewise.
885 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
887 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
888 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
889 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
890 Use a better substitute, by inspecting the output of "ls"
891 rather than just using ":".
892 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
893 rather than AS_EXECUTABLE_P, since we needn't worry about
894 non-regular files here.
896 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
897 due to configuration hassles with this. See Tonya Underwood's report
898 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
899 * doc/autoconf.texi (Special Shell Variables): Likewise.
901 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
902 Stepan Kasal <kasal@ucw.cz>
904 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Don't set BIN_SH.
905 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
907 2006-10-11 Stepan Kasal <kasal@ucw.cz>
909 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
910 initialization which is not inherited through the environment
911 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
912 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
914 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
916 * doc/autoconf.texi (Limitations of Usual Tools): Describe
917 problems with mkdir -p -m.
919 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
921 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
922 comment about ac_cpp_err; it was incorrect, and anyway
923 ac_cpp_err is being removed below.
924 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
925 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
926 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
927 nobody uses it.
928 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
929 with werror_flag and conftest.err and so forth. This is more
930 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
931 and anyway the user shouldn't normally want to see this gorp logged.
932 Problem reported by Ralf Wildenhues.
933 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
934 empty, not 'no', since the rest of the code uses 'test -z'.
936 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
938 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
939 Use a single call to AC_DO_TOKENS rather than multiple, for

945 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
946 than creating a file to use with test -x; this is much faster.
948 2006-10-02 Bruno Haible <bruno@clisp.org>

951 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
953 2006-09-27 Stepan Kasal <kasal@ucw.cz>
955 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

958 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
960 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

966 failed.
968 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.

1080 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

1085 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1086 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.

1090 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1091 works with GNU M4 1.4.3 again; make the normalized form
1092 match the current m4 message; fix the description.

1098 to catch glibc bug 2821
1099 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1101 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1102 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1103 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1104 assume C89.

1126 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1127 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1128 accept files with extension `.f'. For consistency, also prefer
1129 xlf over f77.
1130 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug

1202 deal with LEXLIB.
1203 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1204 didn't work if some values were cached but not others. Test for
1205 broken lex libraries like native ia64-hp-hpux11.22; see
1206 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1207 work around the problem by preferring an empty LEXLIB to -lfl or
1208 -ll. Let the user set LEXLIB='' to indicate no library needed.
1210 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1211 * README: Likewise.
1212 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1376 --help' should mention that `--version' outputs configuration
1377 settings. Report by Bruno Haible.
1379 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1381 Fix test suite failures reported by Pierre in
1382 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1383 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1384 the compiler created a file "b.out" when it didn't create anything
1385 at all.
1386 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1387 Discard stderr too, when invoking the test script.
1389 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1391 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1392 in the restoring of the werror flag.
1394 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1396 * doc/autoconf.texi (Volatile Objects): Be even a little
1397 less skeptical about "volatile", after discussion with
1398 Bruno Haible on bug-gnulib.
1399 (Limitations of Usual Tools): Warn about sed stripping
1400 leading white space from text. From Bruno Haible.
1402 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1404 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1405 compiler complains about it, even if things works after the
1406 complaint. Problem reported by Peter O'Gorman.
1408 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1409 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1410 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1412 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1414 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1415 after -R regardless of host. Patrick Welche reports that this
1416 fixes things on NetBSD 3.99.
1418 * NEWS: Recommend M4 1.4.5.
1419 * README: Likewise.
1420 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1421 * tests/tools.at (autom4te cache): Update wording of diagnostic
1422 to match M4 1.4.5.
1424 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1426 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1427 under AC_C_VOLATILE.
1428 (Volatile Objects): Be a little less skeptical about what
1429 "volatile" means. Derived from thoughts by Ben Pfaff in
1430 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1432 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1434 * doc/autoconf.texi: Fix some typos.
1436 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1438 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1439 more globally, since the 2006-06-30 patch didn't suffice. Problem
1440 reported by Keith Marshall. Also, don't bother with builddir2,
1441 since it shouldn't be needed any more.
1443 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1445 * doc/autoconf.texi (Generic compiler characteristics):
1446 Document AC_COMPUTE_INT. Fix wrong statements on Default
1447 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1449 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1450 (_AC_COMPUTE_INT): Add obsoletion warnings.
1451 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1452 AC_COMPUTE_INT.
1454 * NEWS: Document change.
1456 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1458 * doc/autoconf.texi (Volatile Objects): New section.
1460 * NEWS: Document previous change.
1462 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1464 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1465 Require that long long int be at least 64 bits wide. C99 requires
1466 this and enough programs depend on it so we should check for it.
1467 Bruno Haible reports in
1468 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1469 that long long int is 32 bits wide with some nonstandard compilers.
1470 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1472 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1474 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1475 to a nonexistent file, so that we don't have to worry about
1476 a local site configuration that doesn't use /usr/local.
1477 Problem reported by Keith Marshall in
1478 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1480 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1482 * doc/autoconf.texi: Be more consistent about using @acronym with
1483 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1484 quite right (it talked about "OSF/Tru64", even though the
1485 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1486 and it even mentioned "OSF 4"!) and at this point there's little
1487 reason to talk about OSF any more, since it died in 1994.
1488 (Specific Compiler Characteristics): Simplify example of
1489 negative-size array.
1490 (File Descriptors): Reorder to make the text flow better.
1491 Remove joke about "appreciate the various levels"; I didn't get it.
1492 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1493 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1494 (File Descriptors, Limitations of Usual Tools):
1495 Tone down the advice against renaming or removing open files.
1496 (Limitations of Usual Tools): Add a new section, on 'rm'.
1498 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1500 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1501 -lXt in LIBS, idea from Karsten Hopp; this was due since
1502 this change:
1504 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1505 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1506 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1507 (which belong to Xt, not X itself). See Debian bug 327655.
1509 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1511 * configure.ac (AC_INIT): Bump to 2.60a.
1512 * NEWS: Update.
1514 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1516 Version 2.60.
1518 * configure.ac, NEWS: Update.
1520 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1522 * config/texinfo.tex: Sync from upstream.
1524 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1525 quadrigraph correctly in traces.
1527 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1528 Fix typos.
1530 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1531 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1532 not defined.
1533 * doc/autoconf.texi (Changed Directory Variables): New node,
1534 to document the whole `datarootdir' business a bit better.
1535 * NEWS: Update.
1536 * tests/torture.at (datarootdir workaround): Extend test.
1537 Prompted by report by Alexandre Julliard.
1539 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1541 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1542 when using default mode of IBM C 6 for AIX. Problem and two-line
1543 fix reported by Larry Jones.
1545 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1547 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1548 about literal '${datarootdir}' if a definition is found in the
1549 output file.
1551 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1553 * NEWS: Use "M4" rather than "m4" when appropriate.
1554 Problem reported by Eric Blake.
1555 * doc/autoconf.texi: Likewise.
1556 Use @acronym around BSD, GCC, and GNU when appropriate.
1557 (Why GNU M4): Renamed from "Why GNU m4".
1558 (Redefined M4 Macros): Mention that Posix
1559 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1560 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1561 to int.
1563 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1565 * bin/autom4te.in (handle_output): Do not forbid the empty
1566 pattern.
1567 * tests/tools.at (autoconf: the empty token): New test.
1569 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1571 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1572 calls, so that we do not care whether they are LIFO or FIFO;
1573 in the m4_wrap, do not check which diversion is the topmost
1574 one, just check that the stack is balanced at the end.
1575 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1576 base diversion forever--pop the previous diversion before
1577 opening the new one; consequently, remove the m4_wrap call.
1578 * lib/autotest/general.m4 (AT_INIT): Likewise.
1579 * tests/m4sugar.at: Do not use
1580 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1582 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1583 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1585 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1586 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1587 Rework example of m4wrap token-pasting trouble so that it doesn't
1588 care whether it's LIFO or FIFO.
1589 Fix some "contrary to"s that are awkward in English.
1591 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1593 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1594 to `yes' instead of `int$1_t' if the type is found, for more
1595 consistent configure output (where $1 is the number of bits).
1596 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1597 Suggested by Bruno Haible.
1599 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1600 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1601 with system headers. Report by Bruno Haible.
1603 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1605 * config/config.guess, config/config.sub: Sync from upstream.
1607 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1608 in order to avoid picking up an older installed frozen m4sh.m4f.
1609 Besides an outdated shell startup, this could have been created
1610 by an earlier M4 version with incompatible frozen file format.
1612 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1614 * README: Recommend m4 1.4.4 instead of 1.4.3..
1615 * doc/autoconf.texi: Likewise.
1616 (Special Chars in Names): Say that $(.FOO) is portable, as
1617 suggested by Stepan Kasal.
1618 (Installation Directory Variables, Build Directories):
1619 (Automatic Remaking, Subdirectories, Fortran Compiler):
1620 (Making testsuite Scripts, Defining Directories):
1621 Quote variable usages better.
1622 (Making testsuite Scripts): Add clean-local rule to makefile
1623 snippet, by Eric Blake.
1624 (Installation Directory Variables): Fix table item font.
1625 Reword slightly to clarify. Generalize advice about
1626 not using special characters to include all file-related
1627 vars, not just VPATH.
1628 (Special Chars in Variables): Warn about special characters in
1629 $(srcdir) too.
1630 (Assignments): Clarify default-value example as suggested by
1631 Ralf Wildenhues in
1632 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1633 (Special Shell Variables): Note leading ./ or ../, as suggested
1634 by Eric Blake.
1635 (Limitations of Builtins): Under cd, warn about CDPATH.
1636 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1637 Ralf Wildenhues.
1639 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1641 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1642 `@var', for texi2html.
1643 (Systemology): Some more word wrapping, for DVI output.
1644 (autom4te Invocation): The short option for `--melt' is `-M',
1645 not `-m'.
1647 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1649 * doc/autoconf.texi: More formatting and English tweaks,
1650 many suggested by Ralf Wildenhues.
1651 Reword to avoid "@code{...}'s" and the like, since it's ugly
1652 with Emacs info mode. discontents -> woes.
1653 Put a few "will"s back. time stamp -> timestamp.
1654 side-effect -> side effect.
1656 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1658 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1659 Warn about $@ not persisting. Problem reported by Julien Danjou in
1660 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1661 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1662 Mention other special chars, too.
1664 2006-06-14 Eric Blake <ebb9@byu.net>
1666 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1668 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1670 * doc/autoconf.texi: Some systematic minor improvements, as
1671 follows. Use "makefile" when talking about makefiles
1672 generally (which might be named "makefile" or "Makefile" or even
1673 "foo.mk"), "Makefile" when talking about a specific makefile
1674 called "Makefile". This unclutters the text from weird quotes
1675 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1676 values" rather than "@var{foo}s" and similar constructs containing
1677 "}s". Use "Make rules" rather than "Makefile rules". Minor
1678 English-language improvements. Change the prefix "sub-" to "sub"
1679 and "re-" to "re".
1680 Put blank lines around examples more consistently.
1681 Avoid "rather" and "very" as intensifiers.
1682 Avoid "will" as an auxiliary.
1683 (Limitations of Make): Split this node into....
1684 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1685 (Leading _ in Macro Names, Backslash-Newline-Newline):
1686 (Backslash-Newline Comments, Long Lines in Makefiles):
1687 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1688 (obj/ and Make, make -k Status, VPATH and Make):
1689 (VPATH and Double-colon, $< in Explicit Rules):
1690 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1691 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1692 New nodes, resulting from splitup of Limitations of Make.
1693 All cross-references changed. Raise the top node from
1694 a section to a chapter, and all subnodes accordingly.
1695 Redo the introductory wording to match the new organization.
1696 (Installation Directory Variables): Use an example that is
1697 closer to what Autoconf actually does. Mention that VPATH's
1698 value should not contain metacharacters or white space.
1699 (Fortran Compiler): Fix a VPATH bug in an example.
1700 (Leading _ in Macro Names): Mention that this problem is no longer
1701 of practical concern.
1702 (VPATH and Make): Reword the advice to make it clearer
1703 that Autoconf and Automake support VPATH in non-GNU make, but
1704 many packages have bugs in this area.
1705 ($< in Explicit Rules): Refer to Build Directories rather
1706 than using a (non-VPATH-safe) example.
1707 (Automatic Rule Rewriting): Mention the sort of disaster that
1708 can ensue with Solaris-style rule rewriting with VPATH.
1710 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1712 * doc/install.texi (Compilers and Options): Weaken the
1713 suggestion to use GNU make for VPATH builds.
1715 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1716 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1718 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1719 in regular expression.
1721 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1723 * doc/autoconf.texi (Installation Directory Variables):
1724 Drop extra @samp from `@table @samp' item.
1725 (Limitations of Usual Tools): Comment fix.
1726 Do not nest @samp just to point to other table items.
1727 (Writing testsuite.at) <AT_CHECK>: The second argument to
1728 `@dvar' is already @samp'ed.
1729 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1730 do not use @var in the second argument.
1732 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1734 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1735 $as_shell.exe too. Problem reported by Andreas Buening in
1736 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1738 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1740 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1741 `unused variable' compiler warning, for `-Wall -Werror'.
1742 Reported by Jaap Haitsma in
1743 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1745 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1747 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1748 case the compiler dumps core. Problem reported for
1749 OpenServer 5.0.7 by Tim Rice in
1750 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1751 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1752 Likewise.
1754 2006-06-06 Tim Rice <tim@multitalents.net>.
1756 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1757 "ERROR" only shows up in "make check" output if there is an
1758 error.
1760 2006-06-06 Eric Blake <ebb9@byu.net>
1762 * tests/tools.at (automatically allowed tokens): Fix typo.
1764 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1766 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1768 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1769 typically overflows on x86 CPUs, even though the C standard
1770 requires otherwise.
1772 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1774 * configure.ac (AC_INIT): Bump to 2.59e.
1775 * NEWS: Update.
1777 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1779 Version 2.59d.
1781 * config/texinfo.tex: Sync from upstream.
1783 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1784 seen, invoke libtoolize with `--ltdl' argument.
1785 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1786 * NEWS: Update.
1787 Suggested by Eric Blake.
1789 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1791 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1792 reported by Ralf Wildenhues.

1808 * tests/base.at: Check AC_REQUIRE's error message.
1809 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1810 to...
1811 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1812 AT_CHECK_M4.
1813 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1814 `expout' as the last parameter.
1815 * tests/tools.at: Adapt to the above change.
1817 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1819 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1820 information about race-free implementations of mkdir.
1822 2006-06-04 Eric Blake <ebb9@byu.net>
1824 * bin/autoreconf.in (help): Document M4 environment variable.
1825 * bin/autoconf.as (Usage): Likewise.
1826 * bin/autom4te.in (help): Likewise.
1827 * doc/autoconf.texi (autom4te Invocation): Likewise.
1829 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1831 * NEWS: GNU make now recommended for VPATH builds.
1832 Mention that some macros are now documented to be obsolescent.
1833 * doc/autoconf.texi:
1834 Prefer "current" to "modern" to describe
1835 currently-used (albeit perhaps old-fashioned) hosts.
1836 Mention which ancient features no longer need to be worried about.
1837 setgid -> set-group-ID
1838 setuid -> set-user-ID (these are the Posix terms)
1839 Fix some misuses of "only".

1848 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1849 Mention that these macros are obsolescent.
1850 (Installation Directory Variables): shall -> should
1851 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1852 Mention that it's now safe to use 3 and 4.
1853 (Limitations of Usual Tools): cp -r is now specified by Posix.
1854 Omit longwinded and obsolescent discussion of cp -f.
1855 Modernize discussion of expr, ls.
1856 (Limitations of Make): Modernize discussion of VPATH builds.
1857 Mention $? as a workaround in some cases.
1858 * doc/install.texi (Basic Installation):
1859 Mention "./configure; make; make install" first. Be more
1860 specific about why this file is generic. Remove unnecessary
1861 parens. Remove misleading "only". Remove obsolete advice
1862 about csh. Don't say "configure" takes awhile; say it
1863 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1864 and CC=c99 rather than CC=c89, as these are blessed by current
1865 Posix. Recommend GNU make if doing a VPATH build.
1867 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1869 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1870 examples involving shell prompts.
1872 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1873 and Paul Eggert <eggert@cs.ucla.edu>
1875 * doc/autoconf.texi (Here-Documents): Add details about the
1876 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1877 use "here-documents" instead of "here documents".
1879 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1881 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1883 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1885 * doc/autoconf.texi (File System Conventions): Warn about ":"
1886 anywhere in directory names.
1888 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1890 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1891 about quoting the case statement, just in case.
1892 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1893 was fixed in ksh93g; reported by Ralf Wildenhues.
1895 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1897 * doc/autoconf.texi (System Services): Do not document
1898 overriding EXEEXT via ac_cv_exeext=ext.
1899 (Particular Programs) <AC_PROG_MKDIR_P>:
1900 Document that ${MKDIR_P} understands --.
1901 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1902 comment.
1904 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1906 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1907 argument with leading hyphen. Problem reported by Paul Eggert.
1909 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1911 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1912 about quoting ac_try: quote all of it, if any of it seems suspicious.
1913 This means we don't have to worry about ${ or sed any more.
1914 Also, double-quote the case statement, to work around misuses via
1915 underquoting as reported by Ralf Wildenhues in
1916 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1917 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1918 undocumented and dangerous macro.
1919 Problem reported by Ralf Wildenhues in
1920 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1922 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1924 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1925 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1926 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1928 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1930 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1931 since evidently some packages rely on the old, broken behavior.
1932 Problem reported by Ralf Wildenhues in
1933 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1934 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1935 pre-2006-05-26 definitions, but leave in the comments that
1936 these macros are dangerous and should not be used.
1937 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1938 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1939 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1940 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1941 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1943 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1945 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1946 the use of 'tr', since this is our only use of 'tr'.
1948 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1949 and Paul Eggert <eggert@cs.ucla.edu>
1951 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1952 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1954 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1956 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1957 the output file in the `${datarootdir}' test.
1959 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1960 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1962 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1963 mention of `datarootdir' in the input file(s), but literal
1964 `${datarootdir}' in the output file, and we haven't warned yet,
1965 then warn as well: the user may have (erroneously) used
1966 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1967 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1968 * tests/torture.at (datarootdir workaround): Extend this test.
1969 * NEWS: Update.
1971 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1972 and Paul Eggert <eggert@cs.ucla.edu>
1974 * doc/autoconf.texi (autoheader Invocation): The first argument to
1975 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1976 alternatives and clear up the language a bit.
1978 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1980 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1981 ac_config_guess, ac_config_sub, ac_configure.
1982 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1983 Fix typo that prevented an unnecessary space from being removed.
1984 Problems reported by Ralf Wildenhues in:
1985 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1987 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1989 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1990 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1991 Don't use the term "thread-safe" to talk about mkdir race
1992 conditions, since the problem is more a process than a thread
1993 issue. Problem reported by Stepan Kasal in:
1994 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1995 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1996 the test for 'install' more closely. Look at MKDIR_P first.
1997 Look in the PATH, and at /opt/sfw/bin.
1998 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1999 Don't bother to try mkdir -p, since we already check mkdir --version;
2000 just look at the version number. (There's no easy way to check
2001 for race-free implementations.)
2002 * tests/tools.at (autoconf: subdirectories): Adjust to above
2003 changes, since MKDIR_P now might end in "/mkdir -p".
2005 * doc/autoconf.texi (autoheader Invocation): Mention that the
2006 first arg of AC_DEFINE_UNQUOTED must be a literal.
2007 Problem reported by Ben Pfaff in
2008 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2010 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2011 * doc/autoconf.texi (Special Chars in Variables): New section.
2012 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2013 (Installation Directory Variables): Quote $(datadir) better.
2014 (Limitations of Builtins): Describe some of eval's trickiness.
2016 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2017 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2018 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2019 in front of every arg, not just trailing args. Quote apostrophes.
2020 (_AC_EVAL_ECHO): New macro.
2021 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2022 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2023 removed.
2024 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2025 exposed by quoting of eval argument. Put the command on line line
2026 so it logs better.
2027 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2028 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2029 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2030 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2031 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2032 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2033 Use eval more safely.
2034 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2035 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2036 to be replaced.
2037 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2038 lines, exposed by quoting of eval argument.
2040 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2041 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2043 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2044 initialization of `ac_cv_exeext', do not override it if it was
2045 already set, unless it was set to `no', for compatibility with
2046 Autoconf-2.13, and comment this.
2047 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2048 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2049 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2050 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2051 Document that this test may be overridden by setting
2052 `ac_cv_exeext'.
2054 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2056 Revert these two patches:
2058 2006-04-06 Eric Blake <ebb9@byu.net>
2059 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2060 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2061 2006-04-01.
2063 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2064 Clean up _AC_COMPILER_EXEEXT* macros.
2065 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2066 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2067 ac_file to the name of the default output file and call
2068 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2069 initial `rm' of the candidate files...
2070 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2071 the same list in subsequent `rm' calls, and for the temporary
2072 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2073 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2074 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2075 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2076 no longer needed) by libtool. Make it a cache check.
2077 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2078 copied here by mistake.
2079 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2080 _AC_COMPILER_EXEEXT.
2081 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2082 _AC_COMPILER_OBJEXT directly.
2083 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2085 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2087 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2088 Fix description of how the buggy `sed' works.
2090 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2092 Sync from Automake:
2094 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2095 ENOLCK. Only mention `make -j' when applicable. Only raise
2096 fatal errors when `make -j' is involved. Improve error message.
2098 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2100 * doc/autoconf.texi (Here-Documents): We now know more about
2101 the variable expansion in here documents bug.
2102 Thanks to Tim Rice and Stepan Kasal.
2104 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2105 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2107 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2109 * tests/autotest.at (Multiline command from M4 expansion):
2110 No failure to be expected if the shell quotes newlines in
2111 commands in the `set -x' output. Report by Tim Rice.
2112 * THANKS: Update.
2114 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2116 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2117 expansion in the here-documents used by config.status, as that
2118 runs afoul of the Korn shell version M-12/28/93d bug described in
2119 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2120 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2121 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2123 2006-05-23 Jim Meyering <jim@meyering.net>
2125 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2126 Fix typo introduced with 2006-04-02 change. It reversed the sense
2127 of the test.
2129 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2131 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2132 ac_dB slightly, to save bytes in the script.
2133 Max out at 50 lines, rather than 96; this is more likely
2134 (though not guaranteed) to avoid obscure 'sed' failures.
2136 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2138 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2139 `tr -d -' as bad option argument. Work around this by deleting
2140 an unrelated character.
2141 Report by Tim Rice <tim@multitalents.net>.
2143 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2144 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2145 Stepan Kasal <kasal@ucw.cz>
2147 * doc/autoconf.texi (Particular Programs): Do not promise that
2148 we always prefer the GNU version of the program, and that we
2149 search according to PATH; both rules can have exceptions.
2150 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2151 AC_PROG_SED. Move descriptions of limitations
2152 to the Limitations of Usual Tools section.
2153 (Limitations of Usual Tools) <sed>: Mention script length
2154 limitations with Solaris /usr/ucb/sed.
2155 <grep>: Fix wording for empty alternative. Mention that -c and
2156 -l should not be combined, and that -E and -F should not be
2157 combined.
2159 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2160 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2162 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2163 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2165 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2167 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2168 AC_DEFINE is now passed to m4_pattern_allow.
2169 * NEWS: Mention that; likewise for AC_SUBST.
2170 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2171 the parameter to m4_pattern_allow.
2172 * tests/tools.at: Add a check for that.
2174 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2176 * lib/autoconf/status.m4: Fix typos.
2178 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2180 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2181 only the files that this macro generates.
2183 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2185 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2186 the HP-UX sed limitation of 99 commands, labels do not count.
2187 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2188 in the comment.
2189 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2191 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2193 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2194 Import the following fix from coreutils:
2196 2006-01-13 Jim Meyering <jim@meyering.net>
2198 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2199 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2200 not double-quote uses of that variable, to accommodate the rare
2201 case in which getmntent is available in none of the libraries
2202 checked. This happens at least on FreeBSD 5.0.
2204 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2206 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2207 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2208 some other programs unwisely rely on these undocumented vars.
2209 But put in warning comments about them.
2210 Problem reported by Ralf Wildenhues in
2211 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2212 * NEWS: Document that these variables are intended to go away.
2214 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2216 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2217 and set the language to C++ (analogous to the equivalent Fortran
2218 tests).
2220 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2221 * doc/autoconf.texi (C++ Compiler): Document it.
2222 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2223 * NEWS: Update.
2225 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2227 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2228 that caused config.status to generate 100-command sed scripts; the
2229 portable limit is 99.
2231 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2233 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2234 variable `ac_d' instead of `d' to avoid infringing namespace.
2235 Report by Ralf Menzel.
2237 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2239 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2240 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2241 * tests/tools.at (autoconf: subdirectories): New test, taken from
2242 the corresponding problem report by Ralf Wildenhues in:
2243 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2245 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2246 Quote some uses of shell variables if they might suffer unexpected
2247 globbing. This doesn't fix all instances of quoting problems that
2248 I found, just the easy ones that look safe.
2249 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2250 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2251 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2252 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2253 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2254 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2255 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2256 Likewise.
2257 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2258 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2260 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2262 * bin/autoreconf.in ($help): Reword according to the manual.
2263 Suggested by Olly Betts.
2265 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2266 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2268 * bin/autoreconf.in: Pass the directory argument to
2269 `require_configure_ac'. Fix comment.
2270 * tests/torture.at (Configuring subdirectories): Expose this.
2271 Reported by Olly Betts.
2273 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2275 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2276 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2277 Automake as follows:
2279 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2280 `$configure_in' instead of `configure.in', to preserve
2281 directory component.
2283 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2285 * config/config.guess, config/config.sub, config/texinfo.tex,
2286 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2288 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2290 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2291 test for C99 conformance; (bool) 0.5 is an integer constant
2292 expression, but (bool) -0.5 is not. Problem reported by Fedor
2293 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2295 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2297 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2298 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2299 Warn about obsolete install-sh files. Remove stray sentence
2300 fragment and fix cross reference.
2301 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2302 install -d; this undoes the 2006-05-10 change.
2303 (MKDIR_P): Mark with AN_MAKEVAR.
2304 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2305 that we don't require $INSTALL to be thread-safe. Move comments
2306 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2307 of AC_PROG_INSTALL. Output a message saying that we're checking
2308 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2309 MKDIR_P instead of AC_SUBST.
2310 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2311 Special magic for MKDIR_P, too.
2312 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2313 a dnl.
2314 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2316 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2318 Sync from Automake, as follows:
2320 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2321 * config/install-sh: Initialize IFS, so field splitting isn't
2322 turned off later.
2323 * config/mkinstalldirs: Likewise.
2324 * config/missing: Remove superfluous quotes. Replace all uses of
2325 `[' by `test', for consistency, and for..
2326 * config/missing (sed_minuso, sed_output): New variables.
2327 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2328 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2329 Fixes `missing' to detect `--output' for help2man. Fixes
2330 PR automake/483. Report by Dennis J. Linse.
2331 (autom4te): Document in `missing --help'.
2333 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2335 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2336 * config/install-sh: Don't use 'path' to talk about file names,
2337 as per GNU coding standards. Close a race condition reported by Ralf
2338 Wildenhues and Stepan Kasal. There is still a race condition
2339 on hosts that predate Posix 1003.1-1992, but we can't help this.
2340 Don't mishandle weird characters like space on pre-Posix hosts.
2341 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2342 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2343 AC_PROG_MKDIR_P from AS_MKDIR_P.
2344 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2345 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2346 earlier editions are not (including Automake 1.8.3).
2347 Do not suggest mkinstalldirs for thread-safety.
2348 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2349 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2350 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2351 presence of special characters and race conditions.
2352 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2353 in Autoconf's name space.
2355 2006-05-10 Bruno Haible <bruno@clisp.org>
2356 and Paul Eggert <eggert@cs.ucla.edu>
2358 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2359 from Automake with minor changes.
2360 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2362 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2364 * config/install-sh: Update to Automake CVS version, as follows:
2365 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2366 * lib/install-sh: Simplify the expr implementation of dirname.
2367 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2368 * lib/install-sh: Handle --, and diagnose unknown options.
2370 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2372 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2373 `./autom4te' to create `./testsuite', since the `all' target
2374 will ensure its presence, but `installcheck' should not create
2375 the uninstalled wrappers.
2377 * tests/torture.at (Unusual Automake input files): Skip if we
2378 detect automake < 1.8.
2380 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2382 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2383 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2384 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2385 * NEWS: Update.
2387 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2389 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2390 munge (multiple) white space and other oddities.
2391 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2392 single quotes in variable assignment.
2393 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2394 and similar failures by adding multiple spaces, tabs, and other
2395 special characters.
2396 Report and different test suggested by Francesco Romani
2397 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2399 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2400 single quotes, we only need to search for single quotes; this
2401 both simplifies the search pattern, and makes us less
2402 susceptible to `echo' variations for arguments not containing
2403 single quotes.
2404 (_AC_ARG_VAR_VALIDATE): Likewise.
2406 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2408 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2409 `$*' and IFS concatenation issue with traditional shells and
2410 bash-2.04. Report by Seanster@Seanster.com.
2412 2006-05-03 Bruno Haible <bruno@clisp.org>
2414 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2415 precisely which Mac OS X versions have the od problem.
2417 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2419 * doc/autoconf.texi: Use @option systematically.
2421 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2422 and Bruno Haible <bruno@clisp.org>
2424 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2425 about 'od'.
2426 (Integer Overflow): Mention the special case of integer division
2427 overflow.
2429 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2431 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2432 traditional shells like the Solaris one that do not use the
2433 first IFS character for assembling `$*'.
2434 Prompted by a related report from autoconf_bug@nro.ca.
2436 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2437 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2439 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2440 Mention more problems with the -e option.
2442 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2444 * NEWS: Typo.
2445 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2447 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2448 in URLs to improve DVI formatted output (requires texinfo 4.6).
2449 (System Services, Systemology, Shellology): Likewise.
2450 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2451 output.
2453 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2454 continuous text.
2455 (Runtime): Fix macro argument names to match description:
2456 `action-if-found' -> `action-if-true' and similarly.
2457 (Obsolete Macros): Likewise.
2458 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2459 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2460 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2462 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2464 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2466 * ChangeLog: Typo.
2467 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2468 DVI output.
2470 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2472 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2473 /bin/sh set unsorted output.
2474 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2475 * tests/local.at: Likewise.
2477 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2479 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2480 (Integer Overflow, Null Pointers, Buffer Overruns):
2481 (Floating Point Portability, Exiting Portably): New sections.
2482 (Writing Test Programs): Fix some langauge. Recommend exiting
2483 with status 1, not merely nonzero. Clarify exit declaration.
2484 (Run Time): Move C exit status stuff to new Exiting Portably section.
2485 (Systemology): Mention Posix and levenez. Update v7 reference.
2486 (Portable Shell): Mention the Posix shell.
2488 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2490 * bin/autoconf.as (me): Replace by as_me.
2492 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2494 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2495 since as_me isn't set yet.
2497 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2499 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2500 a few minor bugs in this area.
2502 * doc/autoconf.texi (Programming in M4sh): Comment out the
2503 documentation of AS_BASENAME, for now.
2504 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2505 (Limitations of Builtins) <basename>: Do not refer to
2506 AS_BASENAME.
2507 * bin/autoconf.as (me): Don't use AS_BASENAME.
2508 (dir): Remove the unused variable.
2509 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2510 AS_DETECT_REQUIRED. All uses changed.
2511 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2512 All uses changed.
2513 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2514 (AS_BASENAME): Use "basename --" to protect against leading "-".
2515 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2516 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2517 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2518 (_AS_DIRNAME_PREPARE): Likewise.
2519 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2520 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2521 (AS_DIRNAME): Use "dirname --".
2523 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2525 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2526 of "run time" and "run-time" changed to "runtime", for consistency.
2527 * lib/autoconf/fortran.m4: Likewise (in comment).
2528 * lib/autoconf/functions.m4: Likewise.
2529 * lib/autoconf/general.m4: Likewise.
2530 * lib/autoconf/headers.m4: Likewise.
2532 * doc/autoconf.texi (Run Time): Document the exit status situation
2533 with more accuracy and detail.
2535 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2537 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2538 Archive is not officially `GNU' any more. Update URL.
2539 (Defining Directories): Likewise
2540 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2542 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2544 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2545 newline from the `trap' code to finish `config.log'; the NetBSD
2546 /bin/sh resets the exit status after an empty command, as
2547 documented in doc/autoconf.texi.
2548 Reported by Dalibor Topic <robilad@kaffe.org>.
2550 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2552 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2553 Suggested by Bruno Haible.
2555 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2557 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2558 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2559 Instead, just list the shells that we know work.
2560 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2561 changed. Be more cautious about the _cv_ variable.
2562 * tests/tools.at (Syntax of the shell scripts): Check the
2563 _cv_ variable once, at first, to avoid an internal autoconf error
2564 when sh -n does not work.
2566 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2568 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2570 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2572 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2573 use ">&-" since we're only 99.999% sure that this is portable,
2574 and since the MinGW bug is fixed in a different way.
2575 * lib/autotest/general.m4 (AT_INIT): Likewise.
2577 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2579 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2580 before opening config.log, to avoid hitting a bug on MinGW.
2582 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2584 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2585 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2586 This works around a MinGW bug reported by Eric Paire.
2587 Make sure that all writes to the log file append to it,
2588 rather than possibly losing data.
2589 * lib/autotest/general.m4 (AT_INIT): Likewise.
2591 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2593 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2594 description.
2596 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2598 * NEWS: Update.
2600 * configure.ac (AC_INIT): Bump to 2.59d.
2602 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2604 Version 2.59c.
2606 * Makefile.maint (news-date-check): Do not require a leading `*'
2607 before the release date in NEWS.
2609 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2610 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2612 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2613 the instantiated file do not contain the string 'datarootdir'
2614 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2615 @mandir@, replace the reference '${datarootdir}' by the value.
2616 * tests/torture.at (datarootdir workaround): New test.
2617 * NEWS: Advertise this temporary fixup.
2618 Based on a patch by Bruno Haible, reported and analyzed by
2619 Paul Eggert and Noah Misch.
2621 2006-04-12 Eric Blake <ebb9@byu.net>
2623 * tests/autotest.at (Debugging a failed test): Fix comment.
2625 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2627 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2628 all the changes since 2006-04-07.
2630 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2632 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2633 succeeded, but `ln -s file dir' failed, take care to remove the
2634 leftover target before the next test, to prevent its spurious
2635 failure; also make sure `ln file dir' works before selecting it.
2636 Thanks to Keith Marshall for pointing this out.
2637 * THANKS: Update.
2639 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2640 assignments in `at_debug_args', so that we put them correctly
2641 in the `run' script.
2642 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2643 Reported by Eric Blake.
2645 2006-04-11 Eric Blake <ebb9@byu.net>
2647 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2648 top-level tests after micro-suite has been run. Used in...
2649 (Debugging a successful test, Debugging script and environment),
2650 (Debugging a failed test): ...these new tests. The first of these
2651 is fixed by...
2652 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2653 macro, split out from...
2654 (AT_INIT): ...here, so that using -d also generates a run script.
2655 Document that -d inhibits top-level logging.
2656 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2657 inhibits top-level logging; debug scripts are created.
2659 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2660 check.
2661 * tests/autotest.at (Empty test, Empty check): New test to check it.
2663 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2664 from gcc.
2666 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2668 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2669 the files if a problem appears. Make the empty *.at files
2670 read-only, too. Proposed by Ralf Wildenhues.
2672 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2674 * config/Makefile.am: Add comment to force updated Makefile.in.
2676 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2677 space only patch to this file, this patch causes the Makefile.in
2678 files that include freeze.mk to be updated, and thus have a
2679 newer time stamp again, which in turn makes a pristine CVS
2680 checkout have correct time stamps.
2682 * Makefile.maint (cvs-sv): New macro, to be used..
2683 (config.guess-url_prefix, config.sub-url_prefix)
2684 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2685 point to CVS text checkout of Gnulib files.
2686 (copyright-check): Bump current year.
2687 (announcement): Do not hard-wire `./announce-gen'.
2688 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2689 correctly.
2690 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2691 `chmod +x'.
2692 (wget_files): Update config.guess, config.sub, texinfo.tex by
2693 `wget-update', now that their URLs work again.
2695 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2697 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2698 Problem noted by Paul D. Smith.
2700 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2702 * doc/autoconf.texi: Remove unused words from word list.
2703 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2704 .x-sc_trailing_space: New files.
2706 * doc/standards.texi: Sync from gnulib.
2708 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2709 `LIBOBJDIR' as experimental.
2711 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2712 with a target directory; it's internally implemented as `cp'
2713 anyway, but since Autoconf advertises the possibility to use
2714 a target directory when LN_S is `ln -s', we need to find out.
2715 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2716 analyzed by Keith Marshall <keith.marshall@total.com>.
2718 * THANKS: Update.
2720 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2722 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2723 confdefs.h as-is. In general, if it has backslash-newline or the
2724 like, then it doesn't work either to sort or to remove empty
2725 lines.

2736 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2738 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2739 apostrophe within a single-quoted string, as this is the usual
2740 tradition and is easier to read than '"'"'. Don't rely on the
2741 shell treating "$/" like '$/'. Use a more-consistent indenting
2742 style for the trap.
2744 2006-04-09 Eric Blake <ebb9@byu.net>
2746 * tests/autotest.at (Backquote command substitution),
2747 (Multiline backquote command substitution): Remove mistaken
2748 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2749 applied...
2750 (Parenthetical command substitution, Multiline parenthetical
2751 command substitution): here.

2828 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2830 Revert the patch from 2006-04-01 and only improve
2831 _AS_DETECT_BETTER_SHELL:
2833 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2834 skip nonexistent directories.
2835 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2836 only shell candidates which exist.
2837 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2838 * lib/autotest/general.m4 (AT_INIT): No need to give three
2839 parameters to _AS_PATH_WALK.
2841 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2842 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2844 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2845 distinguish m4sugar macros.
2846 * tests/tools.at (autoupdating with aclocal and m4_include):
2847 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2848 test case by Noah Misch <noah@cs.caltech.edu>.
2850 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2852 Revert my change from 2006-03-17, in other words:
2853 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2854 and DUALCASE=1.
2855 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2856 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2857 it is set.
2859 2006-04-07 Eric Blake <ebb9@byu.net>
2861 * doc/autoconf.texi (Programming in M4sh): Document that
2862 AS_MKDIR_P exits the script on failure.
2863 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2865 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2867 * config/elisp-comp, config/install-sh, config/mdate-sh,
2868 config/missing, config/mkinstalldirs: Sync from Automake.

2884 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2886 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2887 whether `set' quotes correctly: redirect stderr of the tested
2888 `set', and use a subshell, for Ultrix; use `sed' instead of
2889 `grep' for zsh `set' which may write binary output; match only
2890 at the beginning of a line, to avoid false positives.
2891 In order to avoid false positives by unrelated variables with
2892 multiline content, put the dump algorithm in a subshell and
2893 unset all variables containing newlines (except some which are
2894 special to the shell). Warn about cache variables that are
2895 unset.
2897 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2910 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2911 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2913 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2914 shell issue with double-quoted command substitutions of native
2915 commands.
2916 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2917 Marshall.
2919 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2936 * tests/Makefile.am (maintainer-check-posix):
2937 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2939 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2940 ac_config_<foo>s again, sometimes normalized, sometimes not.
2941 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2942 (AC_CONFIG_COMMANDS): Do not do so here.
2943 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2944 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2945 2005-07-25 rewrite. Noticed by Noah Misch.
2947 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2948 _AC_PRESERVE_HELP_ORDER, ...
2949 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2951 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2952 inside m4_expand_once; it is redundant.
2954 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2955 for --help from Cygnus `configure.'
2957 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

2964 * lib/autoconf/status.m4: Replace <space>''<tab> with
2965 <tab><space> where this makes sense.
2967 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)

2970 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2971 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2972 * doc/autoconf.texi (Help Formatting): New node.
2973 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2975 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2977 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,

2989 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2990 empty test suite works.
2991 * tests/autotest.at (Empty test suite): Remove xfail.
2993 2006-04-05 Noah Misch <noah@cs.caltech.edu>

2996 TAGS to ac_config_<foo>s.
2997 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2998 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2999 normalizing it, consistent it with previous releases.
3000 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3002 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3004 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3005 Use simplified args that Eric Blake originally suggested.
3007 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3009 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3010 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3011 Use 'comm' rather than N instances of grep; this also fixes a bug
3012 whereby substrings were incorrectly matched, causing us to not
3013 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3014 (exclude_list): Exclude empty macros.
3015 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

3027 a subdirectory subject to Cygnus `configure'.
3028 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3030 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3031 report request when we have no AC_PACKAGE_BUGREPORT.
3033 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3035 * THANKS: Update.

3065 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3066 to log, point to testsuite output tree.
3068 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>

3096 Clean up _AC_COMPILER_EXEEXT* macros.
3098 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3099 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3100 ac_file to the name of the default output file and call
3101 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3102 initial `rm' of the candidate files...
3103 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3104 the same list in subsequent `rm' calls, and for the temporary
3105 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3106 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3107 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3108 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3109 no longer needed) by libtool. Make it a cache check.
3110 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3111 copied here by mistake.
3112 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3113 _AC_COMPILER_EXEEXT.
3114 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

3887 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3888 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3889 by the function rather than ignoring it.
3890 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3891 comparing its address. Intel's interprocedural optimization was
3892 outsmarting the old heuristic. Problem reported by

3910 Stepan Kasal <kasal@ucw.cz>
3912 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3913 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3914 make its content writable before removing it. Remove an errorneous
3915 comment from the end, where the logs of the failed tests are copied
3916 to the main log file.
3918 2005-09-27 Stepan Kasal <kasal@ucw.cz>

3925 problems if the testsuite were running too fast.
3927 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3929 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

3941 suggested by Ben Elliston. Handle weird characters correctly.
3943 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3945 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3946 calls, so that the final expansion of this macro is shorter.
3947 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3948 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3949 the cleanup there. Use AS_VAR_* macros, to be more general.
3950 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3952 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3954 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

3972 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3974 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3975 in the example. Reported by Bruno Haible.
3976 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3977 "if $undefined_var;" succeeds with my shell.
3979 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3980 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;

3991 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3992 some evil values and relying on the fact that $* concatenates the
3993 parameters by the first character from IFS.

3996 Stepan Kasal <kasal@ucw.cz>

3999 first header appears, define AH_HEADER.
4000 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4001 Update limitations about when to call AC_CONFIG_HEADERS.
4002 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4003 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4004 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4005 ``Configuration Actions''; fix their index entries.
4007 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4008 options correctly. Process N-M as M-N if M is smaller than N.
4009 Process ranges correctly so that N-N will run only N.
4010 Sort and uniquify the tests that will be run. If there is more
4011 than one test, reinsert the banners for the tests.

4017 before passing the macro name to AH_TEMPLATE.
4019 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4020 now opens log after option processing; in particular, --version
4021 and --help do not touch config.log.

4038 Prepend to LIBS, not append, in examples.
4040 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4042 When building in place, set srcdir="."; suggested by Tim Van Holder.
4044 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4045 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4046 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4047 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

4059 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4061 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4062 add "2>&1"; gzip 1.2.4 prints help on stderr.
4064 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4066 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4067 was pushdef'ed twice while popped only once. Push it only once.

4077 * Makefile.maint: Update from Bison.
4079 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4080 "<tab>" in comment, so that the point is understandable.
4082 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4084 Rewrite substantial part of lib/autoconf/status.m4.
4085 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4086 and CONFIG_COMMANDS are not processed in four separate loops.
4087 Instead, there is one main loop. This alows that the common code
4088 is expanded only once, thus config.status (and configure) is smaller.
4090 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4091 the AC_LIST_FILES and cousins macros are no longer used.
4093 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4094 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4095 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4096 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4097 contain the initialization, nor the for loop, nor the associated
4098 commands; all these go to ...
4099 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4100 _AC_OUTPUT_CONFIG_STATUS.
4101 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4102 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4103 (_AC_OUTPUT_FILE): The creation of the sed script ...
4104 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4105 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4106 _AC_OUTPUT_MAIN_LOOP.
4107 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4108 _AC_CONFIG_COMMANDS): Use ...
4109 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4110 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4111 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4112 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4113 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4114 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4115 ... new macros.
4116 (_AC_CONFIG_UNIQUE): Update.
4117 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4118 Replaced by this ...
4119 (_AC_LIST_TAGS): ... new common macro.
4120 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4121 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4122 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4123 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4124 this didn't belong to the `config commands' section.
4125 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4126 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4127 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4128 to the `config commands' section either.
4129 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4130 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4132 ... and many changes to the comments nearby.
4134 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4135 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4136 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4137 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4138 (#define header templates): The comment at the top of the generated
4139 header now includes the name(s) of the source file(s).
4141 Several unrelated small changes:
4143 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4144 parameter to AC_DIAGNOSE.
4145 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4146 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4147 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4148 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4149 with AU::AC_OUTPUT.
4150 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4151 in AC_OUTPUT doesn't double-quote it either.
4152 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4153 parameters.
4155 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4157 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4158 versions of Portland Group compiler produce single- and double-quoted
4159 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4160 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4162 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4164 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4165 This is a corrected version of yesterday's patch.
4167 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4169 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4170 path, too; insert a "===" to emphasize the line.

4173 ac_cv_build_alias to ac_build_alias.
4174 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4176 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4177 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4178 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4179 (AC_ARG_VAR): ... here.
4180 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4181 target_alias.
4183 Keep a list of all precious variables and process them with one simple
4184 for loop, instead of expanding all commands, or, OTOH, complicated
4185 processing of output of "set".
4186 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4187 variable names in new macro...
4188 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4189 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4190 a loop to assign all ac_env_* and ac_cv_env_* variables.
4191 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4192 to INIT_PREPARE.
4193 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4194 its value to shell variable ac_precious_vars and call
4195 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4196 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4197 _AC_ARG_VAR_VALIDATE.
4199 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4200 and the AC_SUBSTs ...
4201 (AC_INIT): ... here.
4203 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4204 the ac_subst_files section in config.log.
4206 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

4216 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4217 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4218 They are generated by the Tru64 v5.1B shell.
4220 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4222 Fix my changes from 2005-07-01; reported by Noah Misch.
4223 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4224 description, the macro now accepts only a single tag.
4225 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4227 Fix cases when the varsions of Autoconf and Autotest don't match.
4228 Reported by Noah Misch.
4229 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4230 at_top_builddir, for compatibility with older autotest.
4231 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4232 is not set, use at_top_builddir, for compatibility with older
4233 versions of autoconf.
4235 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4237 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4238 Problem reported by Patrick Welche.
4240 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4242 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4243 sed substitution command, so that we allow | in program prefixes
4244 and program suffixes. (& is a problem anyway; we're not fixing
4245 that here.)
4246 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4247 configure_input, top_builddir, srcdir, etc.
4248 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4249 PATH_SEPARATOR in AUTOTEST_PATH.
4251 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4253 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4254 for loop over config.site files using `set', to allow
4255 directory names containing IFS characters.

4259 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4260 directories with weird names. Apparently some people like living
4261 on the edge. However, improve the test that "pwd" actually does
4262 report a name for the working directory.

4279 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4281 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4282 document to output the default config_* lists to config.status.
4283 Don't recognize option --file, if the functionality is not there.
4284 Likewise for --header; moreover, recognize --he and --h as shortcuts
4285 for --help in that case.
4287 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4288 matches the order of execution. No code changed.

4309 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4310 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4311 (AC_SUBST): Call it.
4312 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4313 the directory specific variables; but don't call it for configure_input.
4315 2005-06-28 Derek Price <derek@ximbiot.com>
4317 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4318 addition.
4320 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4322 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4323 directory have inherent problems with special characters like spaces,
4324 due to limitations in Make syntax. Problem reported by Alexandre
4325 Duret-Lutz.
4326 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4339 from Justace Clutter.
4340 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4341 variable into diagnostic. Make the diagnostic an error, not a warning,
4342 because we really don't support spaces and suchlike in dir names.
4343 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4344 Don't worry about backslashes in srcdir; it can't happen now.
4345 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4346 Simplify ac_optarg handling.
4347 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4355 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4357 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4358 that '\|' is not allowed in BREs; recommend using newline separated
4359 list of patterns instead of multiple -e options.
4361 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4363 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
4365 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4369 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4371 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4372 b, t, r, w commands require single space, while : cannot have any.
4373 (Special Shell Variables): Fix sed code this in the example.
4374 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4375 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4377 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4378 expand to the empty list. Don't use two pairs of m4_changequote,
4379 it's not necessary.
4381 2005-06-20 Derek Price <derek@ximbiot.com>
4383 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4385 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4387 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4388 * doc/autoconf.texi:
4389 Don't mention Solaris versions so much, if a
4390 problem is common to all extant versions of Solaris. Say "SunOS
4391 4" instead of "SunOS" for SunOS 4.
4392 (awk): Mention more of the limitations of traditional Awk.
4393 (cat): Don't talk about cat -v.
4395 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4397 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4398 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

4400 to be compatible with glibc strverscmp.
4401 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4403 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4404 on Mac OS X 10.4 reported by Peter O'Gorman in:
4405 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4406 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4407 Use shell builtins rather than 'expr', to work around expr bug.
4409 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4411 * doc/autoconf.texi: "filesystem" -> "file system".
4412 "behaviour" -> "behavior".
4413 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4414 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4415 as per POSIX.

4422 to update the man page. That way, we don't have to check in new
4423 man pages every month.
4425 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4426 quotes and backslashes. Patch from Derek Price.

4431 AS_TR_SH.
4433 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4435 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4436 -u, since it outputs chatter if the input files are the same.
4437 Problem reported by Ralf Menzel.
4439 2005-06-08 Derek Price <derek@ximbiot.com>
4441 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4442 renaming them since they are about to be redefined anyhow.
4444 2005-06-08 Derek Price <derek@ximbiot.com>
4446 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4447 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4448 Move m4_undefine to alphabetical order.
4450 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4452 * README: Recommend GNU M4 1.4.3 or later.
4453 * doc/autoconf.texi (Introduction): Likewise.
4454 Reword to avoid some formatting glitches.
4455 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4456 Clarify explanation of HP compiler bug.
4457 Redo example output tp match current CVS snapshot.
4458 Use @example.org in email addresses when the examples
4459 might get inadvertently cut-and-pasted into user code.
4460 Remove example of autom4te usage that doesn't seem to work now.
4461 Use modern AC_INIT (except when the example is meant to be
4462 shown with Autoconf 2.13).
4463 Update ksh info for Solaris 9 and later.
4464 KB -> kB.
4465 Modernize description of Automake versions a bit.
4466 Don't claim a future version of Autoconf is near.

4469 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4471 * doc/autoconf.texi: Add [] to examples, so that the manual
4472 follows its own advice about quoting better.
4473 Reword to avoid some formatting glitches.
4474 * doc/installt.exi: Reword to avoid some formatting glitches.
4476 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4477 Tru64 ksh pattern matching bug. Reported against Libtool by
4478 Albert Chin <libtool@mlists.thewrittenword.com> and
4479 Nicolas Joly <njoly@pasteur.fr>.
4481 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4483 m4_cdr of one-member list was [[]] (one-member list containing an
4484 empty string) instead of [] (an empty list. Callers were skewed to
4485 match this misbehaviour. As a consequence of this:
4486 - m4_foreach([x], [], [foo]) expanded to `foo', while
4487 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4488 This bug has been fixed:
4490 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4491 expand to an empty string; print error msg if called without
4492 an argument list.
4493 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4494 misbehaviour; handle [] and [[]] correctly.
4496 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4498 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4499 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4500 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4502 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4504 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4505 swallow records with more than 99 fields.
4506 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4507 parse the long line.
4509 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4511 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4512 swallow literals longer than 399. Reported by Ralf Wildenhues.
4513 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4514 to workaround this limitation.
4516 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4518 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4519 to gfortran, and make these the first two compiler names
4520 checked (following the general autoconf preference for gcc).
4522 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4524 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4525 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4526 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4528 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4530 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4531 expression of unbounded size when processing the --list
4532 option. This runs afoul of a limit of 399 bytes per regular
4533 expression on AIX. Problem reported by Ralf Wildenhues.
4535 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4537 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4538 * doc/autoconf.texi (Particular Headers): Reword example
4539 for multiline stdbool replacement.
4540 (Setting Output Variables): Reword text a bit. Don't
4541 give all the details about |#_!!_#|.
4542 Reword description of line replacement.
4544 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4546 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4547 now contain newlines, and substituted files must be referenced on
4548 a line alone; the sed scripts to substitute them are now very
4549 different.
4550 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4551 commands can be put in a sed script portably.
4552 * doc/autoconf.texi (Setting Output Variables): Document above
4553 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4554 use of multiline substitution.
4555 * tests/torture.at: No longer expect substitution of newline to fail.
4557 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4559 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4560 From Ralf Menzel (trivial change).
4562 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4564 * tests/local.at: Don't attempt to check for negated character
4565 classes in shell scripts. The test was too brittle.
4567 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4569 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4570 * doc/autoconf.texi (Limitations of Builtins): Document this
4571 limitation.
4573 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4575 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4576 common code; used in many places in the tree.
4577 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4578 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4580 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4582 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4583 messages when ac_unique_file is not found.
4584 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4585 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4586 commands, for consistency with AC_MSG_ERROR and such.
4588 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4590 * bin/Makefile.am: Merge the two rules for creating scripts.
4592 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4594 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4595 obsolete; it was never documented.
4596 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4598 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4600 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4601 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4602 (ac_top_builddir): ... this ...
4603 (ac_top_build_prefix): ... to this; the old name is also kept, for
4604 backward compatibility.
4605 (ac_top_builddir_sub): New variable, without the trailing slash,
4606 always nonempty.
4607 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4608 * doc/autoconf.texi (Configuration Actions): Rename
4609 ac_top_builddir to ac_top_build_prefix.
4610 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4611 at_top_builddir to at_top_build_prefix.
4612 * lib/autotest/general.m4 (AT_INIT): Likewise.
4614 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4616 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4617 of confdefs.h .
4619 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4621 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4622 argument to m4_foreach. I guess it was necessary in the past,
4623 but I think it's a no-op now.
4625 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4627 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4628 ``cat <<_ACEOF'' commands to one.
4629 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4630 * lib/autoconf/status.m4: On various places, use expr instead of
4631 ``echo|sed.''
4632 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4633 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4634 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4635 a range.
4636 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4637 the wrong patterns between ``case'' and ``esac.'' The previous
4638 code had false positives.
4640 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4642 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4643 as on 2005-05-02.
4644 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4645 Mention LIBOBJDIR.

4685 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4687 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4688 check.
4689 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4690 enough arguments, similarly as in m4_bpatsubsts.
4692 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4694 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4695 of absolute paths.
4697 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4699 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4700 for absolute directory names in one loop.
4701 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4702 abbreviations of --version and --debug.
4704 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4706 * doc/autoconf.texi (Autoconf Language): Be more precise about
4707 quoting rules. Problems noted by Stepan Kasal.
4708 Also, throughout this document, be more careful about white space.
4709 "blank", "white space", and "space" all have different meanings
4710 and we should be careful to say what we mean.
4712 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4714 Fix C++ related problems reported by Werner Lemberg.
4715 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4716 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4717 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4718 avoid problems with C++ and throw.
4719 * tests/compile.at: .cpp, not .cc.
4721 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4723 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4725 * doc/autoconf.texi (Generic Functions): Typos.
4727 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4729 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4730 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4731 set by latest automake.
4733 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4735 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4736 outputs 0 on GNU/Linux these days.
4738 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4740 * doc/autoconf.texi (Autoconf Language): Add more description
4741 about quoting heuristics.
4742 (Limitations of Builtins): Describe "set -" problems.
4744 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4746 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4747 not newline.
4749 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4750 by AC_DEFINE; it was a mistake.
4751 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4753 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4755 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4757 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4759 * doc/autoconf.texi (External Software): Quadrigraphs are not
4760 processed correctly in AS_HELP_STRING; avoid this in the examples.
4761 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4762 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4763 comment and reduce m4_default([foo], []) to [foo].
4764 (m4_strip): Update the explanation.
4766 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4768 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4769 Remove core.conftest.* too; it's generated by Tru64 5.1.
4770 Problem reported by Jennis Pruett.
4771 * lib/autoconf/functions.m4
4772 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4773 Don't bother to remove core files; AC_RUN_IFELSE should do that
4774 for you.
4776 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4778 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4780 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4782 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

4785 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4787 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4788 the comment.
4790 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4792 * doc/autoconf.texi (External Software, Package Options): Add
4793 examples showing how to implement --with-* and --enable-* options.
4795 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4797 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4798 as well as configure.in. Problem reported by Gregorio Guidi.
4800 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4802 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4803 pattern for alloca snippet.
4805 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4807 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

4813 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4815 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4816 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4818 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4820 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4821 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4822 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4823 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4824 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4826 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4828 * NEWS: The configure command now warns you if you attempt to use
4829 a directory whose name contains a special character like space,
4830 newline, or "\".
4831 * doc/autoconf.texi (Installation Directory Variables): Allow
4832 "," in file names. Do not use \@; it's not a portable regexp.
4833 * bin/Makefile.am (edit): Likewise.
4834 * lib/Makefile.am (edit): Likewise.
4835 * tests/Makefile.am (edit): Likewise.
4836 * tests/semantics.at: Likewise.
4837 * tests/torture.at: Likewise.
4838 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4839 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4840 * doc/autoconf.texi (File System Conventions): Warn about
4841 unportable file names.
4842 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4843 (AC_INIT): Use it.
4844 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4845 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4846 ac_pwd, and quote srcdir.
4847 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4849 * doc/autoconf.texi: Fix some systematic formatting problems.
4850 ".)" needs a following @: if not at the end of a sentence, and
4851 similarly for "!)". "etc." should be preceded by a comma.
4852 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4854 2005-03-22 Bruno Haible <bruno@clisp.org>
4856 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4857 argument is often called 'build-aux'.
4859 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4861 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4862 macro AC_TRY_LINK is obsolete.
4863 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4864 `AC_CONFIG_FILES'.
4866 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4868 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4869 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4870 from a Common Lisp's `cl'.
4871 (AC_PROG_CXX): Behave according to the documentation: don't
4872 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4873 make the variable CCC precious; use `cl.exe', not `cl'.
4875 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4876 Alexandre Duret-Lutz <adl@gnu.org>
4878 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4879 /dev/null, as "configure" shouldn't read stdin, and this insulates
4880 us from problems (e.g., when testing for "cl"). Also, do this
4881 redirection before invoking "hostname" or "uname", and keep the
4882 original input stream available via...
4883 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4884 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4885 bother with "</dev/null" since it's now done at the top of
4886 'configure'.
4887 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4888 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4889 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4890 * doc/autoconf.texi (File Descriptor Macros): New section.
4891 (Printing Messages): Mention it.
4892 * tests/base.at (Input/Output): New test.
4894 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4896 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4897 newline if neither \c nor -n work, as that would output two
4898 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4900 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4902 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4903 This causes that any required macros inside will get before the if.
4904 * doc/autoconf.texi (autom4te.cache): A typo.
4906 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4908 Undo previous change, except keep the change to
4909 lib/autoconf/programs.m4 that replaced grep with shell
4910 pattern-matching. This is because net-snmp configure reads stdin.
4911 Reported by Noah Misch.
4913 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4915 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4916 from /dev/null, as "configure" shouldn't read stdin, and this
4917 insulates us from problems (e.g., when testing for "cl").
4918 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4919 before invoking "hostname" or "uname".
4920 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4921 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4922 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4923 "</dev/null" since it's now done at the top of 'configure'.
4924 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4925 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4926 Also, replace grep with shell pattern-matching, to save a process.
4928 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4930 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4931 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4932 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4933 compiler.
4935 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4937 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4938 grep -q isn't portable. Improve grep -s explanation.
4939 Problem reported by Dan Manthey.
4941 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4943 * doc/autoconf.texi (Special Shell Variables): Clarify
4944 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4946 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4948 * doc/autoconf.texi: Use @acronym for DJGPP.
4949 Fix some @code's that should have been @env's, and vice versa.
4950 Sort environment variable names.
4951 Mention that shells no longer inherit IFS.
4952 Don't recommend PATH_SEPARATOR=';' so strongly.
4953 Mention that $RANDOM might expand to the empty string.
4954 "symlink" and "soft link" -> "symbolic link".
4955 Improve mktemp description (reported by Bruno Haible).
4957 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4959 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.

5031 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5033 Try not to generated lines of unlimited length, as POSIX places a
5034 2047-byte limit on line length of portable text files.
5035 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):

5094 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5095 Update the long comment explaining it.
5097 m4_require no longer writes an ``is required by'' line to the
5098 execution stack. It contains only one bit of non-redundant
5099 information: that the macro was required, not called. And even
5100 this bit is useless in most situations: have you ever met a macro
5101 which both calls and requires the same macro?
5103 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5104 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5111 (_m4_require_call): Use it.
5112 * tests/m4sugar.at (m4_require): Expect output without the
5113 ``is required by'' messages.
5115 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5117 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5118 rather than x for expr.
5120 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5121 this is safe.
5122 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

5144 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5146 * doc/autoconf.texi (Limitations of Builtins): Clarify that

5149 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5151 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5152 Warn about newline stripping in `` and $(). Update Solaris
5153 version to 9.
5154 (Limitations of Builtins): Use expr "X...", not expr "x...", as

5157 stripping.
5159 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5181 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5183 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5205 (_m4_divert_n_stack): New macro; the expansion is
5206 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5207 otherwise.
5208 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5209 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5210 stored in _m4_divert_diversion or _m4_divert_dump.
5211 (m4_divert_pop): When the parameter is given, compare the symbolic
5212 name with the last diversion pushed on the stack. Previously, the
5213 current diversion was compared with the numeric value of the
5214 diversion given as the parameter.
5215 (m4_require): If the macro hasn't been expanded yet, call ...
5216 (_m4_require_call): this new macro.

5249 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5302 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
5303 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

5430 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
5431 Don't depend on .x file explicitly, since "make" does that for us.
5432 Suggested by Stepan Kasal.
5434 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
5435 Add *.tmp.

5495 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5497 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5498 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5499 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5500 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5502 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5504 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5519 with exactly one parameter.
5521 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5523 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5524 "char c = '\200';" rather than "char c = 0x80;" as the
5525 latter doesn't conform to the strict C standard due to
5526 overflow on signed char hosts.
5528 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5529 to -qlanglvl=ansi. We don't want to disable extensions.

5549 Automake (not without Autoconf).
5550 (Introduction): Mention lists.gnu.org.
5551 * BUGS: Don't mention bugs.gnu.org.
5552 Remove mention of ancient libtool compatibility problem.
5553 * NEWS: Mention that bugs.gnu.org is kaput.

5585 simplify the examples and improve their quoting.
5587 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5590 the $1_found variable, don't test whether the file is executable;
5591 Both things are checked ...
5592 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5593 the former ``test -f''.
5594 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5596 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

5629 Problem reported by Stepan Kasal.
5631 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5633 Fix problems reported by Andreas Buening in:
5634 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

5636 in test makefile.
5637 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

5640 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5642 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5643 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5644 (trivial change). Problem and patch reported by Andrew Church in:
5645 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5647 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5649 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

5652 Also, fix some minor spacing and punctuation bugs.
5654 2004-09-02 Akim Demaille <akim@epita.fr>
5656 * doc/autoconf.texi (Limitations of Builtins): Swap "cd" and

5674 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5675 texinfo.tex for now (done by hand now).
5676 * Makefile.maint (wget_files, cvs_files):
5677 Remove ansi2knr.c; nobody uses it.
5678 (ansi2knr.c-url_prefix): Remove.
5679 (cvs-update): Fix test for failure. I don't know why it ever
5680 worked...
5682 * doc/autoconf.texi: Update URLs, some of which went stale.
5683 Use @uref rather than @href.
5685 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5686 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5688 * config/config.guess, config/config.sub, config/elisp-comp,
5689 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5690 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5692 * NEWS, TODO, configure.ac, bin/autoscan.in,
5693 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5694 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5698 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5699 tests/tools.at, tests/torture.at:
5700 Use "file name" rather than "filename" or "path",
5701 to be consistent with the terminology of the GNU coding standards.
5703 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5705 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5706 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5707 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5708 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5710 More fixes to support spaces in the name of the build directory.
5711 This isn't a complete fix but it's an improvement.
5713 * bin/autoconf.as (autom4te_options): New var.
5714 Use it instead of appending to AUTOM4TE, so that we can allow
5715 spaces in the build directory's absolute name.
5716 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5717 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

5728 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5730 * doc/autoconf.texi (Function Portability): Document isinf and
5731 and isnan. From a suggestion by Kevin Ryde.
5733 * lib/Autom4te/General.pm (END): Return correct exit status even
5734 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5736 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5738 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5739 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5740 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5742 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5744 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5745 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5746 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5747 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5748 * lib/autom4te.in (Automake-preselections): Preselect
5749 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5751 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5753 * lib/autom4te.in (Automake-preselections): Preselect
5754 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5755 trace them.
5757 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5759 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5760 Tru64.
5761 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5762 Document problem with "`""`" in pdksh POSIX mode.
5764 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5766 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5767 with pdksh, too. Problem reported by Patrick Welche via
5768 Gary V. Vaughan.
5769 * doc/autoconf.texi (Shellology): Note that set -o posix is
5770 useful for pkdsh, too.
5772 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5774 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5775 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5776 Don't fail if ENV or BASH_ENV is readonly.
5777 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5778 etc. are read only. Problem reported by Ludovic Courtes.

5784 (trivial change)
5786 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5788 * doc/autoconf.texi (File System Conventions): Warn about
5789 names like "aux". Problem reported by Eric Blake.
5791 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5792 by zero instead of array size, so that we can use any arithmetic
5793 constant expression (instead of requiring an integer constant
5794 expression). This allows us to test expressions like DBL_MAX <
5795 LDBL_MAX, which didn't conform to the C standard using the old
5796 method.
5797 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5798 now that we can do floating-point tests at compile time.
5800 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5802 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5803 and LDBL_EPSILON, as the resulting expression isn't an
5804 integer constant expression and violates the C standard.
5805 Problem reported by Nelson H. F. Beebe. Also, check
5806 for "L" suffix, and check that long double doesn't have
5807 worse range or precision than double, that mixed-mode
5808 arithmetic doesn't generate a diagnostic, that double
5809 constants fit in long double.
5811 2004-06-03 Kevin Ryde <user42@zip.com.au>
5813 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5814 malloc(0) and realloc(NULL,size).
5816 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5817 Bob Proulx.
5819 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5821 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5822 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5823 by Jim Meyering.
5825 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5827 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5828 can be rewritten using if-then-else. Suggested by Bruno Haible.
5830 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5832 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5833 Problem reported by Stepan Kasal.
5835 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5837 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5838 change). Patch reported by Ralf Wildenhues in
5839 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5841 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5842 function F exists if the compiler and linker let you compile an
5843 expression like (F != 0). Recent versions of GCC optimize away
5844 the reference to F in that case, since every function address must
5845 be nonzero, so the link succeeds even if F does not exist.
5846 Problem reported by Manu in
5847 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5849 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5850 "Unix". Many uses changed.
5851 (Limitations of Builtins): Explain better why the ! command isn't
5852 portable.
5854 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5856 * lib/autom4te.in (Automake-preselections): Preselect
5857 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5859 2004-05-19 Kevin Ryde <user42@zip.com.au>
5861 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5862 referencing AC_FUNC_STRERROR_R.
5864 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5865 note pessimistic assumption when cross compiling.
5867 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5869 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5870 (until 2004) invoked subcommands with sh -e, contra POSIX.
5871 Reported by Kevin Ryde.
5873 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5875 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5876 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5877 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5878 `test -f " /usr/bin/grep"', which _always_ failed.
5879 (AC_PROG_SED): Ditto bogus PATH fix.
5880 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5881 requires that grep correctly supports _multiple_ `-e' options, rather
5882 than stating only that grep should accept `-e'.
5884 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5886 Port to C99, which requires that 'exit' be declared.
5888 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5889 to ensure that stdlib.h is included.
5890 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5891 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5892 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5893 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5894 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5895 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5896 when using 'exit' in a test; C99 requires that 'exit' be declared.
5898 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5900 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5901 now prefers 'grep' implementations that accept -e.
5902 (Limitations of Usual Tools): Describe problems of traditional
5903 egrep and fgrep with long input lines, and of traditional grep
5904 with -e.
5905 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5906 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5907 All callers changed. Append /usr/xpg4/bin to the PATH, for
5908 Solaris.
5909 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5910 the user with complaints about multiple -e options.
5911 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5912 Define it with AC_PROG_GREP.
5913 * configure.ac (AC_PROG_GREP): Add.
5914 * lib/freeze.mk (GREP): New macro.
5916 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5918 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5919 a possible candidate only after all others fail, rather than
5920 consulting it first. This improves backward compatibility by
5921 better reflecting the way shell selection occurred in previous
5922 versions of Autoconf, and should help to avoid triggering latent
5923 problems in other packages, such as the one in Automake where zsh
5924 is not handled robustly:
5925 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5926 Although it is not Autoconf's responsibility to work around
5927 problems in Automake, it nevertheless makes sense to avoid
5928 introducing unnecessary incompatibilites.
5930 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5931 Gary V. Vaughan <gary@gnu.org>
5933 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5934 how deeply nested we are when a suitable tool is found, set the
5935 ac_path_TOOL_found flag.
5936 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5937 nested we are in this macro. Break out of all 3 nested loops if
5938 ac_path_TOOL_found is set.
5940 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5942 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5943 of the _AS_PATH_WALK loop too if GNU flavor is found.
5945 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5947 * doc/autoconf.texi (Limitations of Make): Update documentation
5948 for `$<'. New entry `Long lines', based on a report from Simon
5949 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5950 paragraph about DJGPP, based on a mail from Richard Dawe.
5952 2004-04-20 Paul Eggert <eggert@twinsun.com>
5954 * tests/c.at (C keywords): Don't assume that GCC supports
5955 "restrict" and "inline", as sufficiently-old GCC versions do not
5956 (also, GCC configured to be in pedantic C89 mode does not).
5957 Problem reported by Sumit Pandya in:
5958 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5960 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5961 consider -g to work if it generates warnings when plain compiles
5962 don't. Problem reported by Braden McDaniel in:
5963 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5965 * doc/autoconf.texi (Slashes): New section, to document a problem
5966 reported by Jim Meyering in:
5967 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5969 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5970 linker output files before linking, to work around IRIX 6 linker bug.
5971 Problem reported by Rainer Orth in:
5972 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5974 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5976 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5977 best tool so far counter rely on the tool path variable name to
5978 avoid checks for one tool being affected by the results of running
5979 the length check on a previous tool.
5981 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5982 match expression argument, as different greps have different
5983 regular expression flavours.
5984 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5985 literals.
5986 (AC_PROG_EGREP): Pass 'EGREP$'.
5987 (AC_PROG_GREP): Pass 'GREP$'.
5989 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5991 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5992 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5994 2004-03-29 Paul Eggert <eggert@twinsun.com>
5996 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5997 Types, Specific Compiler Characteristics, System Services,
5998 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5999 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6000 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6001 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6002 Likewise.
6003 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6004 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6005 AC_TYPE_OFF_T): Likewise.
6006 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6007 Likewise.
6009 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6010 pacify libtool 1.5.2. Fix quoting problems in sed command.
6012 2004-03-28 Paul Eggert <eggert@twinsun.com>
6014 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6015 now defines HAVE_DECL_TZNAME if it is declared, when
6016 HAVE_STRUCT_TM_TM_ZONE is not defined.
6017 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6018 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6019 for HAVE_TZNAME.
6021 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6023 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6024 superfluous backslashing of quotes (") in sed expressions;
6025 thanks to Paul Eggert.
6027 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6029 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6030 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6031 H. F. Beebe for the bug report.
6033 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6035 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6036 quoted -cmdline argument in Portland Group compiler (bug
6037 reported by Jeffrey J. Barteet).
6039 2004-03-25 Kevin Ryde <user42@zip.com.au>
6041 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6042 (Run Time): ... here, where it's now mentioned.
6044 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
6046 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
6047 inherits from language Autoconf-without-aclocal-m4.
6048 (Customizing autom4te): Adjust example; the cache must now be
6049 disabled for language Autoconf-without-aclocal-m4.
6051 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
6052 Nathanael Nerode <neroden@twcny.rr.com>

6060 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
6061 AC_CHECK_TARGET_TOOLS, and warn for future changes
6062 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
6063 AC_CHECK_TOOLS.
6064 (Specifying Names): Document the reason for these future
6065 behavioral changes.
6066 * tests/mktests.sh: Do not generate tests for the
6067 new macros.
6068 * NEWS: Document these changes.
6070 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6071 they make TeX hang up.
6073 2004-03-15 Paul Eggert <eggert@bogus.example.com>
6075 * NEWS: New macro AC_CHECK_ALIGNOF.
6076 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6077 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6078 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6079 vowel.
6080 (AC_CHECK_ALIGNOF): New macro.
6081 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6082 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
6083 those for sizeof.
6085 2004-03-03 Paul Eggert <eggert@twinsun.com>
6087 * bin/Makefile.am (edit): Don't use $< in a context where
6088 POSIX doesn't require support for it. Use $@.in instead.
6089 Problem reported by Anthony N. Frasso in
6090 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6091 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6093 2004-02-23 Gary V. Vaughan <gary@gnu.org>
6095 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
6096 from the next generation of Libtool.
6097 * lib/autom4te.in (Autoreconf-preselections): Ditto.
6099 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
6101 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
6102 is not always thread-safe. Report from Nathanael Nerode.
6104 2004-02-18 Paul Eggert <eggert@twinsun.com>
6106 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6107 problem on QNX reported by Stephen Rasku in
6108 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6110 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6111 $(m4sh_m4f_dependencies); this removes a FIXME.
6112 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6113 (MAINTAINERCLEANFILES): Split into pieces,
6114 one per related section. Add $(srcdir)/wrapper.in.
6116 2004-02-09 Paul Eggert <eggert@twinsun.com>
6118 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6119 AC_SUBST provides no portable way to escape literal newlines.
6121 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6122 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6123 Darwin uses -lcrt2.o and there's little point to cataloging all
6124 the system variants. Partial fix reported by Andreas Waechter in:
6125 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6126 for bug reported by Nelson H. F. Beebe in:

6129 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
6131 * doc/autoconf.texi (AU_DEFUN): Fix English,
6132 suggested by Paul Eggert.
6133 * lib/autoconf/autoupdate.m4: Correct reference to
6134 acobsolete.m4, suggested by Alexandre Duret-Lutz.
6136 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
6138 * bin/autoupdate.in: Define __file__ so that warnings
6139 refer to the correct file.
6140 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
6141 the behavior of the third argument.
6142 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6143 correctly the behavior of the third argument. Document
6144 what the three macros that AU_DEFUN defines do. Fix
6145 warning message when the third argument includes $0
6146 (reported by Alexandre Duret-Lutz).
6148 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6149 Eric Sunshine <sunshine@sunshineco.com>
6150 Paul Eggert <eggert@twinsun.com>
6152 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6153 (AS_INIT): Output shell initialization there. Removed optional
6154 parameter. Expand _AS_SHELL_FN_SPY.
6155 (AS_INIT_WITH_SHELL_FN): Removed.
6156 (_AS_SHELL_FN_SPY): New macro.
6157 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6158 macros.
6159 (AS_SHELL_SANITIZE): Remove loop to find better shell
6160 and documentation for the parameter.
6161 (_AS_DETECT_BETTER_SHELL): Move it here.
6162 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6163 (_AS_RUN): Move it here, support testing with eval.
6164 (AS_REQUIRE_SHELL_FN): Require shell functions when
6165 it is used.
6166 (_AS_LINENO_WORKS): Put around braces, we do not
6167 trigger the bash bug anymore.
6168 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
6169 use AS_INIT_WITH_SHELL_FN.
6170 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6172 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
6174 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
6175 * doc/autoconf.texi: Don't say that the third parameter
6176 is broken.
6177 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
6178 (AU_DEFUN): Honor the third parameter, create autoupdate
6179 macros with AU_DEFINE.
6180 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
6181 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

6189 * lib/autoconf/status.m4: Remove FIXME.
6190 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
6191 that the macro is not present anymore in the updated
6192 configure.ac.
6193 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
6194 of autoupdate.

6199 copyright years.
6200 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6201 2003 (except 1997) to the list of copyright years. This undoes
6202 the 2003-05-22 change, which removed the older years from the list.
6203 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6205 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6209 grep or ggrep program in PATH that accepts as long lines as
6210 possible.
6211 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6212 AC_PROG_GREP.
6213 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6214 egrep and fgrep respectively if $GREP -E/-F don't work.
6215 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6216 _AC_PROG_GREP, and AC_PROG_SED.
6217 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6218 longest input length accepted by a command.
6219 (AC_PROG_SED): Use it.
6220 * doc/autoconf.texi (Particular Programs): Document the changes.
6221 * NEWS: Updated.
6223 2004-01-27 Paul Eggert <eggert@twinsun.com>
6225 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

6230 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
6231 bin/autoconf.in, config/Makefile.in, config/config.guess,
6232 config/config.sub, config/install-sh, config/mdate-sh,

6245 sources.
6247 2004-01-26 Paul Eggert <eggert@twinsun.com>
6249 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6250 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6251 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6252 not <inttypes.h>. Problem reported by Tim Mooney in
6253 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6254 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6255 Likewise.
6257 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6258 otherwise "make check" fails because it forbids cmp (I guess
6259 because cmp treats files as binary on DOS-like systems).
6261 * tests/mktests.sh: Update copyright date to 2004, since some tests
6262 have changed in 2004.
6264 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6266 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6267 non-truncating sed or gsed program in PATH.
6268 * tests/acprograms.at: Add it.
6269 * doc/autoconf.texi (Particular Programs): Document it.
6270 * NEWS: Updated.
6272 2004-01-15 Paul Eggert <eggert@twinsun.com>
6274 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6275 -std1 disables some useful extensions on Tru64. Problem reported
6276 by N. Lichtmaier in
6277 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6279 2004-01-14 Paul Eggert <eggert@twinsun.com>
6281 * doc/autoconf.texi (Programming in M4sh): Document that
6282 AS_MKDIR_P succeeds if the destination is a symbolic link
6283 to an existing directory.
6284 (Limitations of Usual Tools): Note that mkdir -p might not
6285 succeed on symlinks to directories.
6287 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6289 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6290 * bin/autoheader.in: Grammar fix in message.
6291 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
6292 Test for dir before calling mkdir -p. (trivial changes)
6294 2004-01-13 Eric Blake <ebb9@byu.net>
6296 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
6297 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
6299 2004-01-10 Jim Meyering <jim@meyering.net>

6303 2004-01-09 Paul Eggert <eggert@twinsun.com>
6305 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6306 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6307 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6308 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6309 AC_COMPILE_IFELSE, since we now assume our caller invokes
6310 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6311 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6312 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6313 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6315 2004-01-07 Paul Eggert <eggert@twinsun.com>
6317 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6318 `"'...'"`, as it's confusing (and I suspect it may not work on
6319 some platforms). The code was incorrect anyway, as it assumed
6320 that \$ evaluated to itself in that context. Reported by
6321 Alexandre Duret-Lutz.
6323 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

6375 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6376 -c -o might not work. From a suggestion by Kevin Ryde.
6377 (C Compiler, Generating Sources, Limitations
6378 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6379 Don't put '-o' after non-options, as POSIX doesn't allow this.

6433 functions work.
6434 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6435 does not work.
6436 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6451 them on the fly.
6453 2003-11-24 Akim Demaille <akim@epita.fr>
6455 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6789 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6790 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6792 2003-09-26 Akim Demaille <akim@epita.fr>
6794 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6795 directory for AC_CONFIG_COMMANDS' first argument exists.
6796 This makes valid the invocation of _AC_SRCPATH that follows.
6797 Reported by Eric Sunshine.
6798 * doc/autoconf.texi (Configuration Commands): Adjust.
6800 2003-09-26 Akim Demaille <akim@epita.fr>
6802 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6803 Reported by Ralf Corsepius.
6805 2003-09-26 Akim Demaille <akim@epita.fr>
6807 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6808 arguments.
6809 Actually, use AU_ALIAS.
6810 From Bruno Haible.
6812 2003-09-26 Paul Eggert <eggert@twinsun.com>
6814 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6815 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6816 Problem reported by Eric Sunshine in:

6821 The test suite are sometimes assigning timings incorrectly.
6822 Reported by Henk Krus.
6823 Diagnosed by Nicolas Joly.
6825 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6826 AT_help_all.
6827 Instead of making AT_help a sequence of assignments to grow
6828 $at_help_all, just make AT_help_all be the growing contents of
6829 $at_help_all, and make a single assignment in...
6830 (AT_INIT): here.
6831 (at_times_skip): Flip the meaning and rename as...
6832 (at_times_p): this.
6833 (AT_INIT): When summarizing the test that ran, remove
6834 $at_times_file after use, and check it is present before trying to
6835 use it.
6837 2003-09-25 Akim Demaille <akim@epita.fr>
6839 Version 2.57d.
6841 * bin/Makefile.am (edit): Handle '@configure_input@'.
6842 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6843 (ifnames): chmod -w.
6844 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6845 executables, not bin/ executables! Otherwise all the magic needed
6846 to find non installed files is turned off. This caused a failure
6847 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6848 as found in its environment (sent by tests/autoreconf): pointing
6849 to bin/autom4te that could not find its files.
6850 * tests/mktests.sh: Force the replacement of generated files, for
6851 the sake of "mv" program that are interactive when overwriting a
6852 -w file.
6853 * config/install-sh: Upgrade from CVS Automake.
6855 2003-09-23 Paul Eggert <eggert@twinsun.com>
6857 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6858 versus test -L issues.
6860 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6861 Paul Eggert <eggert@twinsun.com>
6863 Trivial change to support GCC's configuration procedure.
6864 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6865 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6866 about inconsistency if the preprocessor is set to give errors for
6867 any warning.
6868 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6870 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6872 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6873 and XFile.pm from Automake.
6874 * lib/Autom4te/XFile.pm: Update from Automake.
6876 2003-09-12 Akim Demaille <akim@epita.fr>

6883 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6884 from masters.
6886 2003-09-12 Akim Demaille <akim@epita.fr>
6888 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6889 not asm/types.h.
6891 2003-09-11 Akim Demaille <akim@epita.fr>
6893 * doc/autoconf.texi (Header Portability): linux/random.h.
6894 From Peter Hendrickson.
6896 2003-09-10 Akim Demaille <akim@epita.fr>
6898 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6899 willing to edit the output files.
6901 2003-09-10 Akim Demaille <akim@epita.fr>
6903 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6904 and AC_FC_FREEFORM.
6905 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6906 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6908 2003-09-09 Akim Demaille <akim@epita.fr>
6910 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6911 Reported by Gary Vaughan.
6912 * bin/autom4te.in (handle_m4): Likewise.
6914 2003-09-09 Akim Demaille <akim@epita.fr>
6916 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6917 trailing files.
6919 2003-09-07 Paul Eggert <eggert@twinsun.com>
6921 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6922 Improve the accuracy of the wording about obsolescence.
6923 From a suggestion by Ian Lance Taylor in
6924 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6926 2003-09-05 Paul Eggert <eggert@twinsun.com>
6928 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6929 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6931 2003-09-04 Akim Demaille <akim@epita.fr>
6933 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6934 AC_FUNC_WAIT3.
6936 2003-09-04 Akim Demaille <akim@epita.fr>
6938 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6939 (freeze): When exiting, use $exit_code.
6940 * lib/autoconf/fortran.m4: Comment changes.
6942 2003-09-04 Akim Demaille <akim@epita.fr>
6944 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6946 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6948 Add support for newer Fortran dialects. The F77 interface is
6949 unchanged, and continues to support Fortran 77. New FC macros
6950 correspond to all the old F77 macros, with output variables FC,
6951 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6952 available dialect, but older dialects can be specified. There are
6953 new macros AC_FC_SRCEXT to set the source extension, and
6954 AC_FC_FREEFORM to accept free-form source files.
6956 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6957 New macros.
6958 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

6974 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6975 Rewrite in terms of the above.
6976 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6977 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

6983 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6984 Document problems with timestamp resolution that 'make', 'cp -p', and
6985 'touch -r' have.
6987 2003-08-27 Akim Demaille <akim@epita.fr>
6989 * tests/m4sugar.at (cross_warning): Make sure to enable the
6990 output, so that we can track spurious m4sugar output.
6991 * tests/local.at: Require 2.57.
6992 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6993 are defaulted by AT_CHECK anyway.
6994 Use AT_CHECK_AUTOM4TE.
6995 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6996 missing dnl.
6998 2003-08-27 Akim Demaille <akim@epita.fr>
7000 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7001 when -Wobsolete is set.

7080 2003-08-21 Akim Demaille <akim@epita.fr>
7082 First stab at preserving warnings between calls to autom4te,
7083 including when the cache is used.
7085 There are still several issues: (i) there are too many runs of m4
7086 (one for include, one for warnings, and some more), (ii) warnings
7087 spreading on several lines are not handled gracefully, (iii) the
7088 code meant to have the call stack display for errors does not work
7089 (its handling should move from m4 to autom4te).
7091 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7092 Use them.
7093 (@preselect): Add m4_warn.
7094 ($exit_status): Remove, use $exit_code.
7095 ($help): Use Autom4te::ChannelDefs::usage.
7096 (&handle_m4): No longer define the m4_warnings.
7097 At each run, extract and report the warnings.
7098 Always cache the result, including if the exit status is on
7099 failure, since if nothing changes, we should result in the same
7100 failure, hence we can use the cache.
7101 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7102 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7103 Remove.
7104 (m4_warn): Redefine as a do-nothing: it is its invocation that
7105 matters, as warnings are now reported via traces.
7106 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7107 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7108 the latter reveals calls to the former.
7110 Adjust the tests.
7112 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7114 2003-08-21 Akim Demaille <akim@epita.fr>
7116 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
7117 Use them.

7121 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7122 forward order.
7123 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7124 (&parse_warnings): Accept a list of warning requests.
7125 (&usage): Return a string, not a side effect.
7126 (cross): New warning category.
7128 2003-08-21 Akim Demaille <akim@epita.fr>
7130 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7131 (&require_configure_ac): Accept an optional directory argument.
7132 ($configure_ac): Remove.
7133 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7134 (&catfile): Remove.
7135 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7136 * bin/autoscan.in: Adjust.
7138 2003-08-20 Akim Demaille <akim@epita.fr>
7140 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7141 Reported by Alexandre Duret-Lutz.
7143 2003-08-20 Akim Demaille <akim@epita.fr>
7145 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7146 * bin/autom4te: Adjust.
7147 In particular, be Autoconf tools are really silent when properly
7148 working, bind the verbosity of the 'note' channel to $verbose.
7149 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7150 (&xsystem, &contents): Remove, since they are exported by...
7151 * lib/Autom4te/FileUtils.pm: this.
7152 More perldoc.
7153 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7154 * lib/Autom4te/FileUtils.pm: here.
7156 2003-08-20 Akim Demaille <akim@epita.fr>
7158 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7159 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

7209 2003-08-14 Derek Price <derek@ximbiot.com>
7211 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7212 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7213 shorter column three. Add DESCRIPTION to log file content.
7215 2003-08-13 Derek Price <derek@ximbiot.com>
7217 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7218 output.

7262 * lib/autom4te.in (args): Add local.at? for Autotest args.
7263 This change was made on autom4te.cfg which is generated.
7264 Reported by Raja R. Harinath.
7266 2003-06-25 Akim Demaille <akim@epita.fr>
7268 * doc/autoconf.texi (Header Portability): sys/mount.h.
7269 From Gareth McCaughan.
7271 2003-06-23 Akim Demaille <akim@epita.fr>
7273 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7274 not all of them. This fixes 1. the fact that when testing
7275 Autoconf there are many many config.log, 2. the incorrect use of
7276 top_srcdir to find config.log.
7277 Don't mix the detailed output of failed test with the summary of
7278 failures. Rather, append detailed log afterwards.
7280 2003-06-23 Akim Demaille <akim@epita.fr>
7282 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7283 always run: output config.log on $at_group_log.
7285 2003-06-23 Akim Demaille <akim@epita.fr>
7287 * tests/torture.at (#define header templates): Don't use quotes in
7288 C++ comments as it puzzles Emacs' sh font-lock-mode.
7290 2003-06-23 Akim Demaille <akim@epita.fr>
7292 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7293 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7294 * tests/atspecific.m4: Rename as...
7295 * tests/local.at: This.
7296 * tests/suite.at: Move the globals into...
7297 * tests/local.at: here.
7298 * tests/Makefile.am: Adjust.
7299 * doc/autoconf.texi (testsuite Scripts): Adjust.
7301 2003-06-21 Kevin Ryde <user42@zip.com.au>
7303 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7304 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7305 ensuring we add -std1 for full-ANSI.
7307 * doc/autoconf.texi (hdrindex): New macro.
7308 Add index entries for portability of various standard header files.
7310 2003-06-20 Akim Demaille <akim@epita.fr>
7312 * configure.ac: Bump to 2.57b.
7314 2003-06-20 Akim Demaille <akim@epita.fr>
7316 Version 2.57a.
7318 2003-06-20 Akim Demaille <akim@epita.fr>
7320 * bin/autom4te.in: Don't rely on $HOME being defined.
7321 Reported by Marc Espie as PR/233.
7323 2003-06-20 Akim Demaille <akim@epita.fr>
7325 * lib/autotest/general.m4: Use at_times_file only if used.
7326 From Nicolas Joly.
7328 2003-06-20 Akim Demaille <akim@epita.fr>
7330 * config/config.guess, config/config.sub, config/elisp-comp,
7331 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7332 Update from masters.
7334 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7336 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7337 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7338 (TEST_SCRIPT): New diversion.
7339 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7340 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7341 (AT_INIT): Support for expected failures.
7343 2003-06-02 Akim Demaille <akim@epita.fr>
7345 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7346 changes.
7347 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7348 Autoconf nor Automake.
7349 (&contents): New, from Automake.
7350 PODify.
7352 2003-05-28 Paul Eggert <eggert@twinsun.com>
7354 * NEWS, doc/autoconf.texi (Particular Functions),
7355 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7356 is the inverse of localtime.
7358 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7360 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7361 (handle_exec_errors): New function. Work around $! being
7362 altered by WEXITSTATUS.
7363 (xqx, xsystem): Use handle_exec_errors.
7365 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7367 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7368 Do not call `_exit()', simply modify `$?'.
7369 (xsystem): Reset $! before running system, and check it afterward.
7370 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7371 63 for version mismatches.
7373 2003-05-23 Akim Demaille <akim@epita.fr>
7375 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7376 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7377 the middle of a line).
7378 * lib/m4sugar/m4sugar.m4: Likewise.
7379 Remove useless spaces in comments.
7381 2003-05-23 Akim Demaille <akim@epita.fr>
7383 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7384 exit 63, so that we (or Automake's "missing") can tell the
7385 difference with a plain failure.
7386 * doc/autoconf.texi (Notices): Adjust.
7388 2003-05-23 Akim Demaille <akim@epita.fr>
7390 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7391 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7392 White spaces cleanup.
7394 2003-05-22 Jim Meyering <jim@meyering.net>
7395 Paul Eggert <eggert@twinsun.com>
7397 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7398 Remove `#include <stdlib.h>' from the list; we should never
7399 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7400 resulting namespace pollution would cause other tests to fail.
7401 Configure scripts run with some older versions of g++ and HP's
7402 aCC would fail due to such an #include. Problems reported by
7403 Matthew Mueller in <http://bugs.debian.org/120704> and by
7404 Keith Bostic in
7405 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7406 In the test, use the test declaration before including <stdlib.h>,
7407 as that's closer to how it'll be used.
7409 2003-05-23 Akim Demaille <akim@epita.fr>
7411 * doc/autoconf.texi (Header Portability): ucred.h.
7412 From Ian Redfern.
7414 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7416 Overhaul Autotest's logging: generate separate log files
7417 in testsuite.dir/NNN/testsuite.log, and append them to
7418 testsuite.log instead of re-running the test verbosely.
7420 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7421 file descriptor, write 0 to at_status_file instead of setting
7422 at_status=0, initialize some new variables (at_status_file,
7423 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7424 to rerun the tests, instead append the at_group_log to the
7425 at_suite_log when a test fails.
7426 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7427 with the AS_MESSAGE_LOG_FD redirected to stdout.
7428 (AT_CLEANUP): save the output status in $at_status_file
7429 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7430 its original place.
7431 (AT_CHECK): since tests are run with a redirected stdout,
7432 and used to be re-run in verbose mode, turn some $at_verbose
7433 into echo, and don't redirect the output of testing stdout
7434 and stderr.
7436 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7437 the name of the debugging directory and information about
7438 its contents.
7440 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7442 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7443 parameter.
7445 2003-05-22 Akim Demaille <akim@epita.fr>
7447 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

7449 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

7466 Suggested by Jim Meyering.
7468 2003-05-22 Akim Demaille <akim@epita.fr>
7470 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed

7474 2003-05-22 Akim Demaille <akim@epita.fr>
7476 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7507 AC_CHECK_HEADERS_NEW): New tests.
7509 2003-05-17 Akim Demaille <akim@epita.fr>
7511 * lib/autoconf/functions.m4: Use the default includes so that
7512 memcmp be declared before being tested.
7513 Reported by Sander Niemeijer.
7514 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7515 * doc/autoconf.texi (Default Includes): Document
7516 AC_INCLUDES_DEFAULT.
7518 2003-05-17 Akim Demaille <akim@epita.fr>
7520 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7521 * doc/autoconf.texi (Obsolete Macros): Adjust.
7522 Reported by Werner LEMBERG and Debian Bug 190886.
7524 2003-05-16 Akim Demaille <akim@epita.fr>

7528 Reported by Bruno Haible.
7530 2003-05-16 Akim Demaille <akim@epita.fr>

7533 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7534 them uniform, and more robust to Perl special characters.
7535 Reported by Martin Mokrejs.

7555 and truncate.
7557 2003-05-06 Akim Demaille <akim@epita.fr>
7559 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7560 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7561 by aclocal.m4 is changed it might require the importing of another
7562 m4 extension file, i.e., aclocal must be run.
7564 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7565 (&parse_args): Use --force with aclocal if required and supported.
7566 (&autoreconf_current_directory): Use &run_aclocal.

7572 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7573 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7574 argument instead of a file name, so that the request file remains
7575 open during the whole autom4te run.
7576 ($icache_file): New.
7577 (&freeze): Lock the $icache_file.
7579 2003-04-29 Derek Price <derek@ximbiot.com>
7581 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7582 seperator with m4_append_uniq(). It doesn't work.
7583 (AT_CLEANUP): Add `;' to end of at_help_all.
7584 (AT_INIT): Allow --keywords to be specified more than once. When
7585 grepping $at_help_all for keywords, use the field and keyword
7586 seperators to ensure a complete keyword match. Alter at_prev handling
7587 to support the new --keywords behavior.
7589 2003-04-27 Karl Berry <karl@freefriends.org>
7591 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7592 align better with others. I also made some of the individual
7593 entries on one line, for brevity and to make it easier for me to
7594 sort my dir-example file in the Texinfo distribution :).
7596 2003-04-12 Jim Meyering <jim@meyering.net>
7598 * NEWS: Mention the new macro.
7599 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7634 New.
7635 Use them.
7636 * doc/Makefile.am (CLEANFILES): Adjust.
7637 (TEXI2DVI): Make it --batch.
7639 2003-03-31 Derek Price <derek@ximbiot.com>
7641 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7642 which removed the main loop.
7643 Thanks to Akim Demaille.
7645 2003-03-29 Akim Demaille <akim@epita.fr>
7647 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
7648 that starts a GUI.
7649 From Ilya Zakharevich.
7651 2003-03-29 Akim Demaille <akim@epita.fr>
7653 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
7654 documentation to read is Autoconf's.
7655 Suggested by Paul Eggert.
7657 2003-03-28 Akim Demaille <akim@epita.fr>
7659 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
7660 reading the section "Present But Cannot Be Compiled" when the
7661 header causes problems.
7663 2003-03-28 Akim Demaille <akim@epita.fr>
7665 * tests/torture.at (Configuring subdirectories): Require aclocal
7666 1.4, otherwise the test fails, as it does support configure.ac.
7667 This fixes the "test 40 failed" bug reports.
7669 2003-03-28 Akim Demaille <akim@epita.fr>
7671 * doc/autoconf.texi (C Compiler): `#line' portability.
7672 From Paul Eggert and Nelson H. F. Beebe.
7674 2003-03-27 Derek Price <derek@ximbiot.com>
7676 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7677 layout in order to allow scripting around test groups.
7679 2003-03-27 Derek Price <derek@ximbiot.com>
7681 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7682 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7683 use new diversions in preparation for accepting new arguments and

7700 sense. Verbosify the diversion definitions comment.
7702 2003-03-26 Derek Price <derek@ximbiot.com>
7704 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
7705 AS_PREPARE.

7726 file name for the m4 program, when it has an "exe" file extension.

7728 remove the error code during normalization.
7730 2003-02-28 Akim Demaille <akim@epita.fr>
7732 * doc/autoconf.texi (Present But Cannot Be Compiled): New.
7734 2003-02-28 Alexandre Duret-Lutz <adl@gnu.org>
7736 * doc/autoconf.texi (Limitations of Make): Remove the section
7737 about `$<' in inference rules, it was a bogus interpretation of
7738 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7739 Tru64 make in the "target lookup" section.
7740 (Automake): Automake 1.5+ no longer requires special tools to be
7741 present on the developer's host.
7743 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7745 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7746 to a shell that can handle redirection or quoting correctly.
7747 Override SHELL with the shell detected by configure.

7762 When constructing paths with IFS=:, quote the path. If we're
7763 constructing a DOS-style absolute path, we don't want to split it
7764 on the colon.

7815 innocuous variant befor including <limits.h> or <assert.h>. This
7816 works around a bug reported by Albert Chin: HP-UX 11i

7818 gettimeofday and many other functions.
7820 2002-12-03 Paul Eggert <eggert@twinsun.com>
7822 Version 2.57.
7824 * NEWS, configure.ac: Update version.
7826 * doc/fdl.texi: Upgrade to FDL version 1.2.
7828 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7829 nontrivially in main's body, so that f's external declaration is
7830 not optimized away in AIX. This should fix the bug reported by
7831 Martin Frydl in
7832 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

7874 2002-11-14 Akim Demaille <akim@epita.fr>
7876 * Makefile.maint: Sync with Bison, i.e.:
7877 (po-check): Scan .l and .y files instead of the
7878 .c and the .h files that they generate. This fixes the bug
7879 reported by Tim Van Holder in:
7880 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7881 Look for N_ as well as for _. Try to avoid matching #define for
7882 N_ and _.

7903 option. Process --recheck after parsing all options. Pass -q
7904 option to configure on --recheck.

7936 Reported by Ezra Peisach.
7938 2002-11-05 Akim Demaille <akim@epita.fr>
7940 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7941 Remove.
7942 We _have_ to stop using the old compatibility scheme that tried to
7943 avoid useless backslashes because Libtool 1.4.3 contains a
7944 AC_DEFINE([error_t], [int],
7945 [Define to a type to use for \`error_t' if it is not
7946 otherwise available.])
7947 We _have_ to quote the single quote and backslashes with \. The
7948 old compatibility scheme saw that ` was backslashed, and therefore
7949 did not quote the single quote. Hence before this patch, Autoconf
7950 was not compatible with Libtool.
7952 2002-11-04 Paul Eggert <eggert@twinsun.com>
7954 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7973 Support -m/--make.
7974 * doc/autoconf.texi (autoreconf Invocation): Adjust.

7994 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7995 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7996 Make variable, not a shell variable.
7997 Suggested by Bruno Haible.
7999 2002-10-31 Akim Demaille <akim@epita.fr>
8001 * bin/autom4te.in (load_configuration): Reject #args out of any
8002 language.

8018 Suggested by Tim van Holder.

8023 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8024 Problem reported by Bruno Haible.
8026 2002-10-29 Akim Demaille <akim@epita.fr>
8028 * doc/autoconf.texi (Header Templates): Put also in words what the
8029 pictures says to assist free style readers.
8030 (Customizing autom4te): s/--cache=/--cache /.
8032 2002-10-29 Akim Demaille <akim@epita.fr>
8034 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8035 sys/wait.h.

8279 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
8280 words about HP-UX cmp: it was actually a user-written cmp.
8282 2002-10-22 Akim Demaille <akim@epita.fr>
8284 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
8285 are a few warnings.
8286 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
8287 Quote for Perl '' strings, not "".
8288 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8289 strings.
8291 2002-10-22 Akim Demaille <akim@epita.fr>
8293 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
8294 characters is a syntax warning now.
8295 (_AS_QUOTE): Accept $2 as list of characters to quote.
8296 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

8301 `@', to tickle Perl's lists.
8302 Reported by Carlos Velasco.
8304 2002-10-18 Akim Demaille <akim@epita.fr>
8306 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

8316 2002-10-17 Akim Demaille <akim@epita.fr>
8318 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

8339 Because of caching, some files that no longer exist and are no
8340 longer required can still cause errors.
8341 Reported by Alexandre Duret-Lutz.
8343 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8344 to frozen files in @ARGV, as @ARGV must remain being a list of
8345 files. Rather, at M4 call sites, use this...
8346 (&files_to_options): New function.
8347 (&freeze): Use &error.
8348 (&up_to_date): If a file that was included according to the cache
8349 is no longer there, then the output is out dated.
8350 (&main): Don't even check whether a file is up to date is anyway
8351 --force is given.
8352 * tests/tools.at (autom4te cache): New.
8354 2002-10-16 Akim Demaille <akim@epita.fr>
8356 * bin/autoconf.as: Kill dead options.
8357 * bin/autoupdate.in (&parse_args): Kill old options.
8358 * bin/autoreconf.in (&parse_args): Remove dead options.
8359 Factor some code.
8360 (&autoreconf): Report the directories we enter *and leave*, so
8361 that error messages can be easily located, and use GNU Make
8362 format, so that Emacs' compile mode understands us.
8363 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8364 if some file was changed instead of `print'.
8365 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8366 (&parse_args): Remove the dead options.
8367 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

8373 2002-10-11 Akim Demaille <akim@epita.fr>

8376 check for compilability.
8378 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8379 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

8381 (AC_CHECK_HEADER): this.
8383 * lib/autotest/general.m4 (AT_INIT): Include the failed test
8384 numbers in the Subject suggestion.

8396 2002-10-11 Akim Demaille <akim@epita.fr>
8398 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8399 file name to enable parallel executions.
8400 From Sam Varshavchik.
8402 2002-10-08 Akim Demaille <akim@epita.fr>
8404 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8405 aclocal invocation, as Gettext macros might not be visible to
8406 aclocal.
8407 Instead of blindly running autopoint, scan configure.ac (not the
8408 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8409 Reported by Paul D. Smith.
8411 2002-10-08 Paul Eggert <eggert@twinsun.com>
8413 Work around problems found when POSIXLY_CORRECT=1 is set.
8414 None of this seems to have anything to do with POSIX, really,
8415 but it's how Perl getopt works.
8416 * bin/autom4te.in (parse_args): Configure GetOpt with
8417 "permute", too.
8418 * doc/autoconf.texi (Invoking autom4te):
8419 --warning -> --warnings.
8420 * lib/autom4te.in: --warning -> --warnings.

8439 2002-09-28 Akim Demaille <akim@epita.fr>
8441 * tests/torture.at (Configuring subdirectories): Be robust to
8442 users who use config.site to require for a cache: in this case,
8443 the two last configure runs, using two different sets of
8444 arguments, trigger a legitimate error.
8446 2002-09-28 Akim Demaille <akim@epita.fr>
8448 * tests/m4sh.at (Functions Support, Functions and return Support):
8449 New.

8462 (tm_zone): Move their rules to...
8463 * lib/autoconf/types.m4: here, using AN_ macros.
8464 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8465 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8466 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8467 * lib/autoconf/programs.m4: here.
8468 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

8479 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8480 (.m4.m4f): Don't pass --prepend-include, since that's done by
8481 tests/autom4te itself.
8482 * lib/autoscan/Makefile.am: Include freeze.mk.
8483 (autoscan.list): New target --this file is no longer a source.
8484 (autoscan.pre): New file.
8486 2002-09-28 Akim Demaille <akim@epita.fr>
8488 * bin/autoscan.in (@kinds): Make them singular.
8489 Adjust all uses.
8490 (&init_tables): When --debug, report the list of rules to ease
8491 tracking changes in autoscan.list.
8492 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8494 2002-09-28 Akim Demaille <akim@epita.fr>

8505 * lib/autoscan/identifiers, lib/autoscan/makevars,
8506 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8507 `functions' line is now prefixed with `function:'.
8508 * bin/autoscan.in (&init_tables): Adjust.
8510 2002-09-28 Akim Demaille <akim@epita.fr>
8512 From now on, autoscan files must always map a macro name to a
8513 word: there is no `default' macro for autoscan.
8515 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8516 all.
8517 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8518 explicit.
8520 2002-09-28 Akim Demaille <akim@epita.fr>
8522 * bin/autoscan.in (%c_keywords): Remove.
8523 (&used): Keep only track of the words we might be interested in.

8554 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8555 Reported by Ralf Corsepius.
8556 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8558 2002-09-26 Akim Demaille <akim@epita.fr>
8560 Single suffix rules and seperated dependencies are not portable.
8562 * doc/autoconf.texi (Installation Directory Variables): Update.
8563 (Limitations of Make): Some about `Single Suffix Rules and

8573 2002-09-24 Paul Eggert <eggert@twinsun.com>

8578 * bin/Makefile.am (SUFFIXES, .in): Remove.
8579 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

8582 2002-09-16 Akim Demaille <akim@epita.fr>
8584 i960 compilers create `b.out' files by default.
8585 Reported by Ralf Corsepius.
8587 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

8606 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest

8608 Suggested by Guido Draheim.
8610 2002-09-13 Akim Demaille <akim@epita.fr>
8612 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8613 (chdir_init) might hang when stat'ing mounted directories.

8616 2002-09-12 Akim Demaille <akim@epita.fr>
8618 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8619 the lists.
8621 2002-09-12 Akim Demaille <akim@epita.fr>
8623 * doc/autoconf.texi (Defining Symbols): Present two different
8624 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

8629 * doc/autoconf.texi: Review grammar and punctuation.

8634 grammatical typos.
8635 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8636 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8637 is obsolescent.
8639 2002-09-11 Akim Demaille <akim@epita.fr>
8641 * doc/autoconf.texi (Questions): Rename as...

8657 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8658 `duplicates', since the algorithm was too naive and could keep
8659 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8660 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8661 Reported by Ralf Corsepius.

8663 cases.
8665 2002-09-09 Akim Demaille <akim@epita.fr>

8671 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8672 directory definition.
8673 Reported by Andreas Schwab and Jim Meyering.
8675 2002-09-06 Akim Demaille <akim@epita.fr>

8678 precious variables are.
8679 Suggested by Pontus Skoeld.
8681 2002-09-05 Akim Demaille <akim@epita.fr>
8683 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8684 (ifnames, autoscan, autom4te): Since we don't only depend on
8685 configure.ac variables (such as VERSION etc.), but also on prefix
8686 and so forth, depend on Makefile, not configure.ac.
8687 Reported by Alexandre Duret-Lutz.
8688 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8690 2002-09-05 Kevin Ryde <user42@zip.com.au>
8692 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

8710 * configure.ac: Bump to 2.53d.

8712 as of today, on Automake's team suggestion.
8714 2002-09-03 Akim Demaille <akim@epita.fr>
8716 Version 2.53c.

8727 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8728 Also, tweak grammar: s/make sure to/be sure to/.
8730 2002-09-02 Paul Eggert <eggert@twinsun.com>
8732 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

8737 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8738 Reported by Raja R. Harinath.
8739 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8740 * bin/autoupdate.in: Use error instead of die.
8742 2002-09-01 Paul Eggert <eggert@twinsun.com>
8744 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8745 ordinary shell concatenation rather than echo+tr+sed command that
8746 runs afoul of a long-line-related sed bug in Solaris 8.
8748 * bin/autoheader.in (parse_args): --warning -> --warnings.
8750 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8751 stdout, as traditional "ls" does.
8752 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8753 _AC_COMPILER_EXEEXT_O): Likewise.
8754 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8756 * bin/autoconf.as: Add --prepend-include option. This patch was
8757 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8758 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8760 * bin/autoconf.in, configure: Regenerate.
8762 * doc/autoconf.texi (Special Shell Variables): Mention
8763 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8765 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8766 MAILPATH and set PS1, PS2, PS4 to default values, to work
8767 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8768 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8769 the Autoconf documentation specifies; fall back to "unset" only if
8770 this fails. Use a shell for-loop for this rather than an m4 loop,
8771 to shorten the output script.
8773 2002-08-30 Paul Eggert <eggert@twinsun.com>
8775 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8776 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8777 for the CDPATH problem. Document PWD.
8778 (Limitations of Builtins): Document the problem that "cd $foo" and
8779 "ls $foo" may refer to different directories in shells conforming
8780 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8781 example, since the old example is now out of date.
8783 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8784 FOO" and "ls FOO" talk about different directories; this catches
8785 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8786 spaghetti.
8788 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8789 of rolling our own unset.
8790 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8791 in practice we needn't worry about CDPATH if unset doesn't work.
8793 * Makefile.in, aclocal.m4, bin/Makefile.in,
8794 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8795 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8796 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8797 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8798 tests/Makefile.in: Regenerate with Automake 1.6.3.
8800 * config/config.guess, config/config.sub, config/mkinstalldirs:
8801 Update.
8803 * configure: Regenerate with self.
8805 2002-08-30 Kevin Ryde <user42@zip.com.au>
8807 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8808 default output.
8810 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8812 * bin/autom4te.in (Request::load): Correctly test for "do" read
8813 failure.
8815 2002-08-29 Akim Demaille <akim@epita.fr>
8817 * lib/Autom4te/General.pm (&xqx): New.
8818 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8819 hand, which is not portable.
8820 (&error): New.
8821 * bin/autom4te.in: Use them.
8822 Use &error instead of die.
8823 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8824 Adjust.
8826 2002-08-17 Paul Eggert <eggert@twinsun.com>
8828 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8829 default list of compilers to try, since it was long ago superseded
8830 by the ksh fc builtin. Suggested by Steven G. Johnson.
8832 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8834 * doc/autoconf.texi (Invoking autom4te): End the option table,
8835 fixing a bug introduced by the previous patch.
8836 (Limitations of Make): Add a 'target lookup' subentry in the
8837 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8839 2002-07-29 Mark D. Roth <roth@feep.net>
8841 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8842 options and use $AUTOM4TE_PATH.
8843 * doc/autoconf.texi: Remove documentation of autom4te
8844 --include-envvar and --site-macro-subdir options and document
8845 use of $AUTOM4TE_PATH.
8846 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8847 arguments from each language section.
8849 2002-07-29 Paul Eggert <eggert@twinsun.com>
8851 * doc/install.texi: Include copyright symbol in copyright notice.
8853 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8854 Replace with:
8855 (AM_MAKEINFOFLAGS): New macro.
8856 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8857 * Makefile.am (INSTALL): Use the new macros.
8858 Use -o rather than --output, since "missing" does not grok --output.
8860 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8862 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8863 comments do not always work. Never trust the exit status of
8864 `make -k'.
8866 2002-07-24 Kevin Ryde <user42@zip.com.au>
8868 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8869 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8871 2002-07-23 Paul Eggert <eggert@twinsun.com>
8873 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8874 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8875 apparently treats PATH="nonexistent" as if it contained ".".
8876 Bug reported by Stefan `Sec' Zehl.
8878 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8880 * doc/autoconf.texi (Limitations of Make): Mention the special
8881 handling of the obj/ directory by BSD make.
8883 2002-07-20 Kevin Ryde <user42@zip.com.au>
8885 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8886 backslashes.
8888 2002-07-19 Akim Demaille <akim@epita.fr>

8897 2002-07-18 Akim Demaille <akim@epita.fr>
8899 Version 2.53b.
8901 2002-07-18 Akim Demaille <akim@epita.fr>
8903 * config/config.guess, config/config.sub: Update.
8905 2002-07-18 Akim Demaille <akim@epita.fr>
8907 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8908 Automake's parts.
8910 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8911 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8912 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8914 2002-07-18 Akim Demaille <akim@epita.fr>,
8915 Alexandre Duret-Lutz <duret_g@epita.fr>
8917 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8918 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

8927 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8928 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8929 latter was not run.
8931 2002-07-17 Akim Demaille <akim@epita.fr>
8933 * lib/Autom4te/General.pm (find_file): Browse the directories in
8934 the order they are given.

8954 macro directory, remove note that include path directories are
8955 used in reverse order, and document --prepend-include option.
8956 * lib/autom4te.in: Use --prepend-include instead of --include.
8957 * tests/wrapsh.in: Use --prepend-include instead of --include.

8995 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
8997 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8998 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8999 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
9000 so that Emacs setups GNU style for perl-mode and cperl-mode.
9002 2002-06-27 Paul Eggert <eggert@twinsun.com>
9004 * config/install-sh: Quote $src. Prefer || to test's -o option,
9005 as per "Limitations of Builtins".
9006 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9007 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9009 * tests/mktests.sh: Use grep instead of fgrep, as per
9010 "Limitations of Builtins".
9012 2002-06-15 Paul Eggert <eggert@twinsun.com>
9014 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9015 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9016 so that we consistently test the just-built programs.
9017 * tests/wrappl.as: Likewise.
9019 2002-06-12 Paul Eggert <eggert@twinsun.com>
9021 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
9022 name, so that symlinks to 'autoconf' work properly. Bug reported
9023 by Bruno Haible.
9024 * bin/autoheader.in (AUTOM4TE): Likewise.
9025 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9026 * bin/autoscan.in (autom4te): Likewise.
9027 * bin/autoupdate.in (autom4te): Likewise.
9029 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9030 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9031 on Solaris 2.5.1.
9033 2002-06-11 Andreas Schwab <schwab@suse.de>
9035 * doc/autoconf.texi: Add more dir entries.
9037 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9039 * bin/autom4te.in ($cache): Don't define using `$me', the name
9040 of the cache should not depend on the name under which autom4te
9041 was installed.
9043 2002-06-07 Akim Demaille <akim@epita.fr>
9045 * tests/tools.at (autoconf: forbidden tokens, basic)
9046 (autoconf: forbidden tokens, exceptions): Adjust to the change of
9047 words in autom4te.in.
9049 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9051 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9052 _AC_LANG_PROGRAM_C_F77_HOOKS.
9054 2002-06-07 Akim Demaille <akim@epita.fr>
9056 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
9057 rename as...
9058 (AC_REPLACE_FNMATCH): this.
9059 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
9060 AC_FUNC_FNMATCH_GNU.
9062 2002-06-07 Akim Demaille <akim@epita.fr>
9064 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
9065 Rosetta Stone for Unix.
9067 2002-06-07 Akim Demaille <akim@epita.fr>
9069 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9070 suggest m4_pattern_allow.
9071 Suggested by Adam J. Richter.
9073 2002-06-07 Akim Demaille <akim@epita.fr>
9075 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
9076 ac_config_libobj_dir.
9077 (AC_CONFIG_LIBOBJ_DIR): New.
9078 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9079 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
9080 Use ac_config_libobj_dir to find the replacement files.
9081 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
9082 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
9083 (AC_REPLACE_FNMATCH_GNU): these.
9084 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
9085 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
9086 * tests/mktests.sh (ac_exclude_list): Don't check
9087 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
9089 2002-06-06 Paul Eggert <eggert@twinsun.com>
9091 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9092 if ln doesn't work.
9093 * NEWS: Likewise.
9094 * doc/autoconf.texi (Configuration Links): Likewise.
9095 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
9097 2002-06-05 Paul Eggert <eggert@twinsun.com>
9099 * config/config.guess, config/config.sub, config/texinfo.tex:
9100 Update from masters.
9102 2002-05-29 Paul Eggert <eggert@twinsun.com>
9104 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
9105 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
9106 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

9113 * lib/m4sugar/Makefile.am (check-local): Likewise.
9114 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
9115 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
9117 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
9118 * doc/autoconf.texi (Particular Programs): Document them.
9119 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
9120 * NEWS: Likewise.
9122 2002-05-27 Paul Eggert <eggert@twinsun.com>
9124 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
9125 * NEWS, doc/autoconf.texi (Particular Types): Document it.
9126 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
9127 instead of AC_MBSTATE_T, which never existed.
9129 2002-05-23 Akim Demaille <akim@epita.fr>
9131 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9132 version of Autoconf that is discussed.
9134 2002-05-22 Paul Eggert <eggert@twinsun.com>
9136 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9137 from the default list of compilers to try. Suggested by
9138 Kate Hedstrom.
9139 * NEWS: Document the above.
9140 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9142 2002-05-17 Paul Eggert <eggert@twinsun.com>
9144 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9145 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9146 This improves on an earlier suggestion by H. Peter Anvin.
9148 2002-05-16 Paul Eggert <eggert@twinsun.com>
9150 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9151 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9152 Both macros now accept an optional source-dir arg.
9153 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9155 * NEWS: Document this.
9156 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9158 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9159 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9160 not for GNU extensions; this undoes part of the 2000-11-03 change,
9161 reverting to 2.13-compatible behavior.
9162 Add new optional argument DIR.
9163 (AC_FUNC_FNMATCH_GNU): New macro.
9165 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9167 2002-05-08 Paul Eggert <eggert@twinsun.com>
9169 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9170 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9171 and it causes a 'test' syntax error if it fails.
9172 Bug reported by Stephen Gildea.
9174 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9175 If prototypes are supported, use them to check this at compile-time,
9176 instead of trying to check it at run-time. If we must do a run-time
9177 check, assume that setvbuf is standard when cross-compiling, as
9178 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9179 Bug reported by Paul D. Smith.
9181 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9182 argument specifying location of getloadavg.c. This removes a
9183 FIXME. This idea was taken from Jim Meyering's implementation in
9184 textutils.
9185 * doc/autoconf.texi (Particular Functions): Document this.
9186 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9187 that's what the code does; this fixes a bug reported by
9188 Paul D. Smith.
9190 2002-05-03 Akim Demaille <akim@epita.fr>
9192 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9193 autopoint instead of gettextize.
9194 ($uses_alocal): Rename as...
9195 ($uses_aclocal): this.
9196 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9197 Suggested by Bruno Haible.
9199 2002-05-03 Akim Demaille <akim@epita.fr>
9201 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9203 2002-04-29 Paul Eggert <eggert@twinsun.com>
9205 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9206 files to be 1 second older; just set them to be the same time.
9207 Also, sleep 1 second after the first aclocal, to work around
9208 problems with sub-second time stamps on the input files.
9210 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9212 * doc/autoconf.texi: Mention "set -e -x" lossage
9213 under node "Limitations of Builtins".
9215 2002-04-29 Akim Demaille <akim@epita.fr>
9217 * doc/install.texi: Better wording for setting variables when
9218 running configure.
9219 From Christian Cornelssen.
9221 2002-04-29 Akim Demaille <akim@epita.fr>
9223 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9224 of lack of $LINENO support, then the test will compare the $LINENO
9225 in testsuite vs. the lineno in the test file. This is wrong, of
9226 course.
9227 Be sure to protect it.
9228 Reported by Patrick Welche.
9230 2002-04-25 Akim Demaille <akim@epita.fr>
9232 * doc/autoconf.texi (Obsolete Macros): Typo.
9233 Reported by Vladimir Volovich.
9235 2002-04-25 Akim Demaille <akim@epita.fr>
9237 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9238 than some of the input files, hence, on the second run of aclocal,
9239 if some of its input are younger, make them older.
9240 Suggested by Paul Eggert.
9242 2002-04-25 Akim Demaille <akim@epita.fr>
9244 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9245 Thanks to Paul Eggert.
9247 2002-04-25 Akim Demaille <akim@epita.fr>
9249 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9250 and ac_subst_vars be sh variables containing the list of
9251 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9252 DEFAULT diversion.
9253 (_AC_INIT_PREPARE): Use them to log them.
9254 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9255 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9256 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9257 _AC_SUBST_FILES and _AC_SUBST_VARS.
9258 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9260 2002-04-24 Akim Demaille <akim@epita.fr>
9262 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9263 autoheader, so that automake does not complain about a missing
9264 config.h.in that was to be created.
9266 2002-04-23 Akim Demaille <akim@epita.fr>
9268 * bin/autoheader.in (parse_args): --warning takes an argument.
9269 Fixes PR/220.
9271 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9273 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9274 and bb.out when cleaning up.

9280 2002-04-22 Akim Demaille <akim@epita.fr>
9282 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9284 2002-04-22 Akim Demaille <akim@epita.fr>
9286 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9287 comma.
9288 Reported by Gregory Giannoni.
9290 2002-04-22 Akim Demaille <akim@epita.fr>
9292 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9293 Fixes false failures on Darwin.
9295 2002-04-21 Paul Eggert <eggert@twinsun.com>

9299 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9302 2002-04-20 Paul Eggert <eggert@twinsun.com>

9317 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
9318 Minor spelling and grammar fixes.
9320 * doc/autoconf.texi: Follow the outline suggested in the GNU
9321 Sample Texts sections of the Texinfo 4.2 manual. Most
9322 importantly, this makes sure that the copyright notices appear in
9323 all output formats. You probably need Texinfo 4.2 to generate
9324 the manual now.
9326 Fix some bugs when using "$@" when there might be zero positional
9327 arguments in cases where this matters.

9347 * tests/c.at: We can't have zero arguments, so remove workaround
9348 that is not portable to Zsh.
9350 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9352 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9353 from aclocal.m4 too.
9355 2002-04-12 Akim Demaille <akim@epita.fr>
9357 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9359 2002-04-10 Akim Demaille <akim@epita.fr>
9361 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9362 workaround for ${1+"$@"}.
9363 * doc/autoconf.texi (Shell Substitutions): Explain it.
9364 From Oliver Kiddle and Peter Stephenson.
9366 Have M4sh perform minimal shell sanitizing.
9368 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9369 part into...
9370 (_AS_PREPARE): this new macro.
9371 (AS_PREPARE): New.
9372 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9373 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9375 Adjust Autoconf and Autotest.
9377 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9378 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9379 * lib/autotest/general.m4 (AT_INIT): Likewise.
9380 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9381 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9382 AS_SHELL_SANITIZE.
9384 Use this M4sh to generate Autoconf's shell scripts.
9386 * tests/wrapsh.as: New, precursor of wrapsh.in.
9387 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9388 on Autotest and M4sh.
9389 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9390 (wrapsh.in): New target.
9391 * bin/autoconf.as: New, precursor of autoconf.in.
9392 (autoconf.in): New target.
9394 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9397 with indented comments in rules.
9399 2002-04-09 Andreas Schwab <schwab@suse.de>
9401 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9402 ac_top_builddir when setting ac_abs_top_builddir.
9404 2002-04-06 Kevin Ryde <user42@zip.com.au>
9406 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9407 (Portable Shell): Cross reference to Systemology.
9409 2002-04-05 Akim Demaille <akim@epita.fr>
9411 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9412 directories when descending in a SUBDIRS.
9413 Reported by Ezra Peisach.
9415 2002-04-04 Andreas Schwab <schwab@suse.de>
9417 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9418 contains no literal separators.
9420 2002-04-03 Akim Demaille <akim@epita.fr>
9422 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9423 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9424 Use dnl, not the KILL diversion.
9425 Extracted from...
9426 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9427 (AC_CONFIG_LINKS): here.
9428 Adjust.
9429 Don't use the KILL diversion, as it kills spurious output, which
9430 results in failures being hidden.
9431 Use m4_defn where appropriate.
9432 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9433 after the second argument.
9434 Use m4_defn.
9435 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9436 syntax, as it is provided by M4sugar.
9437 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9439 2002-04-03 Andreas Schwab <schwab@suse.de>
9441 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9442 expanded if $# <= 2.
9444 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9445 aclocal.
9447 2002-04-03 Akim Demaille <akim@epita.fr>
9449 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

9451 Also recognize *.bb and *.bbg as compilation byproducts.
9452 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9453 (_AC_COMPILER_OBJEXT): Use them.
9454 Fixes Debian #138666.
9456 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9458 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9460 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9461 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9462 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9463 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9464 (AC_C_CONST): Same.

9468 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9469 AC_C_CROSS.

9474 _AS_MKDIR_P_PREPARE.
9476 2002-03-28 Kevin Ryde <user42@zip.com.au>
9478 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9479 to avoid versions of HP C which don't allow that.
9481 2002-03-27 Paul Eggert <eggert@twinsun.com>
9483 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9484 (AS_SHELL_SANITIZE): Invoke it.
9485 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9487 2002-03-26 Akim Demaille <akim@epita.fr>
9489 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9491 2002-03-26 Akim Demaille <akim@epita.fr>
9493 * doc/autoconf.texi (Introduction): The GNATS base moved.
9495 2002-03-25 Paul Eggert <eggert@twinsun.com>
9497 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9498 as POSIX requires, as it doesn't work with Zsh.
9499 * doc/autoconf.texi (Assignments): Document the problem.
9501 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9503 * doc/autoconf.texi (Limitations of Make): Mention more issue
9504 about VPATH, overriding of macros in sub-makes, and handling of
9505 SHELL.
9507 2002-03-21 Paul Eggert <eggert@twinsun.com>
9509 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9510 problem with here-document buffer boundaries.
9512 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9513 when reinvoking the shell, to work around problems with installers
9514 who put strange things like "cd" commands in their environments.
9516 2002-03-19 Akim Demaille <akim@epita.fr>
9518 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9519 From Aaron Ucko.
9521 2002-03-19 Akim Demaille <akim@epita.fr>
9523 * bin/autoscan.in (scan_file): Specify the location in `&used'
9524 invocations.
9525 From Nicolas Joly.

9529 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9530 From Nishio Futoshi.
9532 2002-03-19 Akim Demaille <akim@epita.fr>
9534 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9536 2002-03-18 Paul Eggert <eggert@twinsun.com>
9538 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9539 (Limitations of Usual Tools): Add mkdir section.
9541 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9542 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9543 back on AS_DIRNAME to compute prefixes otherwise; this is
9544 roughly what mkinstalldirs does. That way, we need not have
9545 our own filename disassembler. The old disassembler did not
9546 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9548 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9549 Create at_test_all by a series of assignments,
9550 not by a single assignment of a long string. The latter causes ksh
9551 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9552 presumably because of a buffer overrun.
9554 2002-03-14 Paul Eggert <eggert@twinsun.com>
9556 * lib/autotest/general.m4 (at_times_skip):
9557 Renamed from at_times. Now a boolean.
9558 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9559 says 'times: not found'.
9561 2002-03-14 Akim Demaille <akim@epita.fr>
9563 * bin/autoreconf.in (&study_gettextize): New.
9564 (&autoreconf): Handle newest gettextize.
9565 Rerun aclocal if needed.
9566 Suggested by Andreas Schwab.
9568 2002-03-13 Akim Demaille <akim@epita.fr>

9572 2002-03-13 Akim Demaille <akim@epita.fr>
9574 * doc/autoconf.texi (Header Portability): New.
9575 Add information about stdint.h and inttypes.h from Paul Eggert.
9577 2002-03-13 Akim Demaille <akim@epita.fr>
9579 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9580 -p'.
9581 From Bob Proulx.
9583 2002-03-12 Akim Demaille <akim@epita.fr>
9585 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9586 m4_require.
9588 2002-03-11 Andreas Schwab <schwab@suse.de>
9590 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9591 does not do it if --with-lispdir is given.
9593 2002-03-08 Akim Demaille <akim@epita.fr>
9595 Version 2.53.
9597 2002-03-08 Akim Demaille <akim@epita.fr>
9599 * doc/autoconf.texi (Subdirectories): Clarify that the
9600 subdirectory should exist.
9602 2002-03-08 Akim Demaille <akim@epita.fr>
9604 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9606 2002-03-08 Akim Demaille <akim@epita.fr>
9608 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9609 aliases the actual variables, and modifications of the former
9610 affect the latter.
9612 2002-03-08 Akim Demaille <akim@epita.fr>
9614 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9615 because of C-c: have m4 output in tmp files, then mv them.
9617 2002-03-08 Akim Demaille <akim@epita.fr>
9619 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9620 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9621 * bin/ifnames.in: Copyright update.

9625 * doc/autoconf.texi (Invoking autom4te): New.
9627 2002-03-05 Akim Demaille <akim@epita.fr>
9629 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9630 Kevin Ryde.
9632 2002-03-05 Akim Demaille <akim@epita.fr>
9634 Version 2.52i.
9636 2002-03-04 Akim Demaille <akim@epita.fr>
9638 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9639 * lib/autoconf/general.m4 (AC_INIT): More informative error
9640 message for LIBOBJ.
9642 2002-03-04 Akim Demaille <akim@epita.fr>
9644 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9645 parallel builds.
9647 2002-03-04 Akim Demaille <akim@epita.fr>
9649 * doc/autoconf.texi (Transforming Names): Equality between target
9650 and host is irrelevant.
9651 (Specifying Names, Canonicalizing): Remove all references to the
9652 backward compatibility hooks. Rather, collect them all into...
9653 (Hosts and Cross-Compilation): this new section.
9654 * doc/install.texi (System Type): Ditto.
9655 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9656 that `--host' implies cross-compilation.
9658 2002-03-04 Akim Demaille <akim@epita.fr>
9660 * doc/autoconf.texi (Evaluation Macros): New.
9661 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9662 useless.
9663 (_m4_foreach): Define the variant with immediate evaluation so
9664 that it contains exactly the items, not an expression which
9665 evaluation is the current item.
9666 (m4_re_string, m4_re_word): Don't over quote them.
9668 2002-03-04 Akim Demaille <akim@epita.fr>
9670 Instead of having stacking `shift's evaluated at the end, let
9671 `foreach' loops immediately evaluate them.
9673 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9674 $*. This is the n-th time I change my mind, but hopefully this is
9675 the last...
9676 (m4_lquote): New.
9677 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9678 efficient.
9679 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9680 it was only a hack for m4_text_wrap.
9681 (m4_car2): Remove, replaced by...
9682 (m4_cdr): New.
9683 (_m4_foreach): Adjust.
9684 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9685 m4_bpatsubst for clarification.

9720 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9721 translate \r\n to \n.
9723 2002-02-07 Akim Demaille <akim@epita.fr>
9725 Version 2.52h.
9727 2002-02-07 Akim Demaille <akim@epita.fr>
9729 Fix Autoconf PR/209.
9730 Also reported by Frank Denis.
9732 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9734 2002-02-07 Akim Demaille <akim@epita.fr>
9736 Fix Autoconf PR/207:
9737 AC_PREFIX_PROGRAM fails with dashed program names
9739 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9740 variable when looking for the prefix program.
9741 Now it also works for shell variables.
9743 2002-02-07 Akim Demaille <akim@epita.fr>
9745 * doc/autoconf.texi (Limitations of Builtins): More about
9746 case/esac.
9748 2002-02-06 Akim Demaille <akim@epita.fr>
9750 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9751 case/esac, some shells don't support it.
9752 Reported by Zack Weinberg.
9753 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9755 2002-02-06 Akim Demaille <akim@epita.fr>
9757 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9758 sure not to introduce newlines in at_groups.
9759 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9761 2002-02-06 Akim Demaille <akim@epita.fr>
9763 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9764 is not available.
9766 2002-02-05 Paul Eggert <eggert@twinsun.com>
9768 * doc/autoconf.texi (Specific Compiler Characteristics):
9769 Describe HP-UX cc bug workaround more accurately.
9770 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9771 not unsigned long.
9772 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9773 cross-compilers, too. This undoes some of the most recent change
9774 to this file.
9776 2002-02-05 Akim Demaille <akim@epita.fr>
9778 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9779 to make sure they are up to date when `check' is run.
9781 2002-02-05 Akim Demaille <akim@epita.fr>
9783 * doc/autoconf.texi (Making testsuite Scripts): Document
9784 package.m4.
9786 2002-02-05 Akim Demaille <akim@epita.fr>
9788 * lib/freeze.mk: New.
9790 2002-02-05 Akim Demaille <akim@epita.fr>
9792 Implement `autom4te --freeze'.
9794 * bin/autom4te.in (&freeze): New.
9795 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9796 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9798 2002-02-05 Akim Demaille <akim@epita.fr>
9800 * bin/autom4te.in (&parse_args): Implement `frozen files are
9801 optional are the sum of the previous files on the command line'.
9802 Also, pass `--reload-state=' on them, so...
9803 (handle_m4): don't.
9804 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9805 (M4sh): Rely on M4sugar.
9806 (Autotest, M4sh, M4sugar): Use frozen files.
9808 2002-01-31 Akim Demaille <akim@epita.fr>
9810 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9811 * doc/autoconf.texi (Initializing configure): Adjust.
9813 2002-01-30 Akim Demaille <akim@epita.fr>
9815 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9816 alphanumeric to `-' instead of `_'.
9818 2002-01-30 Akim Demaille <akim@epita.fr>
9820 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9821 for plain code, the other for cross-compilation code. The latter
9822 is now run with GCC only.
9823 * doc/autoconf.texi (Compilers and Preprocessors): New.
9825 2002-01-30 Akim Demaille <akim@epita.fr>
9827 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9828 values.
9829 * doc/autoconf.texi (Initializing configure): Explain how to
9830 change AC_INIT default values.
9832 2002-01-29 Akim Demaille <akim@epita.fr>
9834 * tests/torture.at (Configuring subdirectories): Use configure.in,
9835 so that aclocal 1.4 works.
9836 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9838 2002-01-28 Akim Demaille <akim@epita.fr>
9840 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9841 needs an argument.
9843 2002-01-28 Akim Demaille <akim@epita.fr>
9845 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9846 AUTOTEST_PATH *after* it was set.
9847 Don't put `.' in the PATH: the user should be precise and `./' if
9848 needed. In addition, given that the test suite does some `cd', if
9849 `.' is in the path, the `tested programs' sections will report
9850 programs found in the test suite's directory, while during the
9851 tests (performed in their own directory), these programs are no
9852 longer visible. In other words, the results is confusing and
9853 useless.
9854 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9856 2002-01-24 Akim Demaille <akim@epita.fr>
9858 Version 2.52g.
9860 2002-01-24 Akim Demaille <akim@epita.fr>
9862 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9863 * doc/autoconf.texi: Finally add Akim as an author.
9865 2002-01-24 Akim Demaille <akim@epita.fr>
9867 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9868 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9869 Bourne. Use /bin/sh.
9870 From Andreas Buening.
9872 2002-01-24 Akim Demaille <akim@epita.fr>
9874 * config/config.guess, config/config.sub, config/texinfo.tex:
9875 Update from masters.
9877 2002-01-24 Akim Demaille <akim@epita.fr>
9879 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
9880 * config/auxdir.m4, config/cond.m4, config/depend.m4,
9881 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
9882 * config/missing.m4, config/sanity.m4, config/select.m4,
9883 * config/strip.m4: Remove, to ease sync'ing with any version of
9884 Automake.
9886 2002-01-24 Akim Demaille <akim@epita.fr>
9888 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9889 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9890 Reported by Geir Ove Myhr.
9892 2002-01-21 Akim Demaille <akim@epita.fr>
9894 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9896 2002-01-21 Akim Demaille <akim@epita.fr>
9898 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9899 message on invalid options.
9900 * bin/autom4te.in (parse_args): Don't use
9901 Autoconf::General::getopt with non valid options.
9903 2002-01-17 Jim Meyering <meyering@lucent.com>
9905 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9906 $ac_cv_exeext so we don't use an old, invalid, cached value.
9908 2002-01-11 Akim Demaille <akim@epita.fr>
9910 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9911 Meyering.
9912 * doc/autoconf.texi (Function Portability): Document the strnlen
9913 limitation.

9917 2002-01-06 Akim Demaille <akim@epita.fr>
9919 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9920 package.m4, since is really depends upon configure.ac, not
9921 configure.
9922 * doc/autoconf.texi (testsuite Scripts): Adjust.
9923 * tests/Makefile.am (package.m4): New.
9924 EXTRA_DIST it since its a source.
9926 2002-01-06 Akim Demaille <akim@epita.fr>
9928 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9929 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9930 and PACKAGE_BUGREPORT from here...
9931 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9932 arguments.
9933 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9934 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9935 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9936 * tests/tools.at (autoheader): Adjust.
9937 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9939 2002-01-06 Akim Demaille <akim@epita.fr>

9943 2002-01-03 Akim Demaille <akim@epita.fr>
9945 * doc/autoconf.texi (Output): Improved wording regarding use of
9946 AC_OUTPUT.
9947 From Olly Betts.
9949 2001-12-18 Kevin Ryde <user42@zip.com.au>
9951 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9952 sometimes needing writable input.
9954 2001-12-17 Jim Meyering <meyering@lucent.com>
9956 * doc/autoconf.texi (New Macros): Tweak wording.
9958 2001-12-14 Akim Demaille <akim@epita.fr>
9960 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9961 trailing files, don't apply `-rf' to files which might not be
9962 created by configure (core, core.*, and *.core), but just `rm -f'.
9963 Suggested by Jonathan Kamens.
9965 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9967 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9969 2001-12-14 Akim Demaille <akim@epita.fr>
9971 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9973 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9975 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9976 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9977 abs_srcdir, top_srcpath to abs_top_srcdir.
9978 (_AC_OUTPUT_FILES): Adjust.
9979 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9980 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9981 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9983 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9985 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9986 C/Fortran linking on HP/UX, by extracting the Fortran library
9987 search path from the LPATH line in the $F77 -v output.
9989 2001-12-12 Kevin Ryde <user42@zip.com.au>
9991 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9992 forbidden file descriptors table.
9994 2001-11-26 Akim Demaille <akim@epita.fr>
9996 * bin/autoscan.in (%c_keywords): Build it at top level.
9997 Map to 1 in order to simplify its uses.
9999 2001-11-26 Akim Demaille <akim@epita.fr>
10001 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10002 Remove $filepath, useless.
10003 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10004 variables, they are really part of the tokens.
10005 Split the input line on spaces and then look for tokens.
10006 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10007 because of `lex$U.$(OBJEXT)'.
10008 (&scan_files): Use "@list" instead of join.
10009 * doc/Makefile.am (CLEANFILES): Add *.fns.
10011 2001-11-26 Akim Demaille <akim@epita.fr>
10013 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10014 Remove, replaced by...
10015 * tests/wrappl.in: Be common for all the Perl executables.
10016 In particular autoscan and autoheader want -I.
10017 * configure.ac: Adjust.
10018 * lib/autoscan/headers: errno.h is portable.
10020 2001-11-26 Akim Demaille <akim@epita.fr>
10022 * bin/autoscan.in (used): New.
10023 Use it.
10025 2001-11-26 Akim Demaille <akim@epita.fr>
10027 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10028 directives.
10029 (&scan_sh_file): Remove a duplicate pattern.
10030 (&check_configure_ac): Use long options.
10031 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10033 2001-11-26 Akim Demaille <akim@epita.fr>
10035 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10036 Before, having a line containing the opening of a multi line
10037 comment made the whole line be ignored.
10039 2001-11-26 Akim Demaille <akim@epita.fr>
10041 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10042 (testsuite Scripts): Be one of its subsection.
10043 (Autotest Logs): New.
10045 2001-11-26 Akim Demaille <akim@epita.fr>
10047 Test groups are now run two directories deeper.
10049 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10050 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10051 at_top_builddir.
10052 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10053 top_srcdir, builddir and top_builddir.
10054 Use `at_*dir' relatively to the directory containing the
10055 suite, use `*dir' when relatively to the current group dir.
10057 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10059 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10060 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10061 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10062 spelling errors.
10064 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10066 * doc/autoconf.texi (Using System Type): Add an example of `case
10067 $host' usage so people quit using `case $target' everywhere.
10069 2001-11-22 Akim Demaille <akim@epita.fr>
10071 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10072 spotted by Jim Meyering.
10074 2001-11-16 Paul Eggert <eggert@twinsun.com>
10076 This patch implements a `long double' suggestion by Oliver Kiddle.
10078 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10079 static, to catch errors if the value isn't known at compile-time
10080 and the compiler supports dynamic arrays. Change its name from
10081 `_array_' to `test_array' to avoid potential name clashes.
10082 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10083 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10084 better than double. Catch a bug in GCC 2.95.2 x86.
10085 * doc/autoconf.texi (C Compiler): Document the above.
10086 * NEWS: Likewise.
10088 2001-11-13 Akim Demaille <akim@epita.fr>
10090 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10091 hand.
10092 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10094 2001-11-13 Akim Demaille <akim@epita.fr>
10096 * lib/autotest/general.m4 (AT_INIT): After having run the test
10097 group, go back to the initial directory, not to at_suite_dir.
10099 2001-11-13 Akim Demaille <akim@epita.fr>
10101 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10102 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10103 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10104 option.
10105 (AT_CHECK_CONFIGURE): Use absolute paths.
10106 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10107 The problem is still the old one: there is no means in M4 (that I
10108 know about) to create a defining macro, because there is no means
10109 to create `$1' etc., therefore, the defining macro ``swallows''
10110 all the arguments meant to the defined macro.
10112 2001-11-13 Akim Demaille <akim@epita.fr>
10114 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10115 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10116 configure.ac.
10117 * tests/aclocal.m4: Remove, as it is no longer used.
10119 2001-11-13 Akim Demaille <akim@epita.fr>
10121 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10122 variable names when referring to a single test group, or to
10123 `suite' when referring to the whole test suite.
10124 `at_last_test' is removed: m4 compute at_format itself.
10125 (at_stdout, at_stder1, at_stderr): New variables.
10126 (AT_CHECK): Use them.
10128 2001-11-13 Akim Demaille <akim@epita.fr>
10130 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10131 in PATH.
10132 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10133 Do it as soon as a test fails, don't wait till the end of the test
10134 suite.
10135 Don't remove $as_me.[0-9]*, since these files no longer exist.
10137 2001-11-13 Akim Demaille <akim@epita.fr>
10139 * tests/tools.at: Use absolute paths, since we are no longer run
10140 in place.
10142 2001-11-13 Akim Demaille <akim@epita.fr>
10144 Now that tests are running in their own private dir, there is no
10145 need to list the files to remove at the end of tests groups.
10147 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10148 (AT_data_files, at_data_files): Remove.
10149 (AT_CLEANUP, AT_DATA): Simplify.
10150 (AT_INIT): Adjust.
10151 Remove the group dir if !debug && !failed.
10152 * tests/atspecific.m4: Adjust.
10154 2001-11-13 Akim Demaille <akim@epita.fr>
10156 Start a new layout for Autotest: `testsuite' creates
10157 `testsuite.dir' in which the at-check-line etc. files are to be
10158 found, and `testsuite.dir/003' where the test group 3 is run.
10160 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10161 at_check_line_file, at_format, at_test_normalized, at_group_dir
10162 are new variables.
10163 Create the directories.
10164 Use absolute paths for at- files.
10165 (AT_CHECK): Adjust.
10167 2001-11-11 Michael Matz <matz@kde.org>
10169 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10170 (m4_car2): New.
10171 (m4_car): Properly quote arguments.
10173 2001-11-13 Akim Demaille <akim@epita.fr>
10175 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10176 with stricter rules on LIBOBJS.
10178 2001-11-12 Paul Eggert <eggert@twinsun.com>
10180 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10181 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10182 __PROTOTYPES too.
10184 2001-11-12 Akim Demaille <akim@epita.fr>
10186 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10188 2001-11-12 Akim Demaille <akim@epita.fr>
10190 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10191 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10192 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10193 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10194 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10195 specify to what the macro should be defined (typically to 1).
10197 2001-11-12 Akim Demaille <akim@epita.fr>
10199 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10200 From Jim Meyering.
10202 2001-11-12 Akim Demaille <akim@epita.fr>
10204 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10205 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10206 definition used by Automake where LEX is +/- "${missing} lex" and
10207 `missing' itself contains variables.
10209 2001-11-12 Akim Demaille <akim@epita.fr>
10211 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10212 Now that M4sh pushes BODY, the comments were output at the end of
10213 the test suites.
10215 2001-11-08 Akim Demaille <akim@epita.fr>
10217 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10218 that we can trace macros from aclocal.m4.
10219 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10220 obsoleted, and redirect to the former anyway.
10221 Reported by Ralf Corsepius.
10223 2001-11-08 Akim Demaille <akim@epita.fr>
10225 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10226 processed only if present.
10227 * tests/torture.at (Configuring subdirectories): Use autoreconf
10228 instead of successive calls to autoconf.
10229 Add a nonexistent subdirectory to exercise the patch above.
10230 Reported by Ralf Corsepius.
10232 2001-11-08 Kevin Ryde <user42@zip.com.au>
10234 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

10243 (handle_output): Use it.
10244 Read m4_pattern_forbid with messages.
10246 2001-11-05 Akim Demaille <akim@epita.fr>
10248 * bin/autom4te.in (--normalize): Remove.
10249 * lib/autom4te.in: Adjust.
10251 2001-11-05 Akim Demaille <akim@epita.fr>
10253 * tests/Makefile.am (testsuite): Rename this target as...
10254 ($(TESTSUITE)): this.
10255 From Nicolas Joly.
10257 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10259 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10260 the --prefix option, also remove it's argument.
10262 2001-11-05 Akim Demaille <akim@epita.fr>
10264 * doc/autoconf.texi (testsuite Invocation): Update.

10275 File::Spec.
10276 Use and export them.
10277 (&find_configure_ac): Optionally take a directory where to look at.
10278 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10279 the arguments.

10285 2001-11-03 Akim Demaille <akim@epita.fr>
10287 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10288 (@export_forward_subs): New.
10289 Add basename, dirname, and fileparse.
10290 (@EXPORT): Adjust.
10291 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10292 Don't look for aclocal flags if we already know aclocal is not
10293 used.
10294 Move aclocal.m4t only if it exists.
10295 Reported by Ezra Peisach.
10297 2001-11-03 Akim Demaille <akim@epita.fr>
10299 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10300 passed on command line, defaulting to ./configure.ac if present.
10301 (&maybe_autoreconf, File::Find): Remove, unused.
10302 (&autoreconf): If autoconf is not used, don't try to trace.
10304 2001-11-02 Akim Demaille <akim@epita.fr>
10306 * configure.ac: Bump to 2.52g.
10308 2001-11-02 Akim Demaille <akim@epita.fr>
10310 Version 2.52f.
10312 2001-11-02 Akim Demaille <akim@epita.fr>
10314 * config/config.guess, config/config.sub, doc/standards.texi:
10315 * config/lispdir.m4: Update from masters.
10316 * configure.ac: Bump to 2.52f.
10318 2001-11-02 Akim Demaille <akim@epita.fr>
10320 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10321 Don't run aclocal when aclocal.m4 is not from aclocal.
10322 From Ezra Peisach.
10323 Don't run libtoolize and gettextize if --install is not given.
10325 2001-11-01 Paul Eggert <eggert@twinsun.com>
10327 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10328 be invoked before _AS_LINENO_PREPARE.
10329 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10330 than character ranges.
10332 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10333 invoking AS_BASENAME. Set the locale variables to 'C' if
10334 possible, as POSIX requires this to get the traditional
10335 behavior.
10336 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10338 2001-10-31 Paul Eggert <eggert@twinsun.com>
10340 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10341 with {}, as that triggers a bug in Bash 2.05.
10343 (_AS_LINENO_PREPARE): Use Sed rather than
10344 Awk. Fix the sed prepass to work even if there are multiple
10345 instances of $LINENO on the same line. Do not substitute for
10346 other variables like $LINENOT. Do not check file dates; such a
10347 check is unreliable on sufficiently fast machines, and removing
10348 the check makes the code simpler and more reliable. Check for
10349 output and chmod failures.
10351 * doc/autoconf.texi (Special Shell Variables): Document
10352 the above.
10354 2001-10-31 Akim Demaille <akim@epita.fr>
10356 * tests/Makefile.am (atconfig): Remove this target, Automake
10357 handles it now.
10359 2001-10-31 Akim Demaille <akim@epita.fr>
10361 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10362 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10363 provided, while it is optional.
10364 * configure.ac: Adjust.
10366 2001-10-26 Paul Eggert <eggert@twinsun.com>
10368 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10369 lib/Autom4te/Struct.pm:
10370 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10371 with 5.005_02.
10373 * doc/autoconf.texi (Special Shell Variables): Document some
10374 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10376 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10377 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10378 eval $LINENO is not portable in practice.
10380 2001-10-24 Akim Demaille <akim@epita.fr>
10382 * lib/Autom4te/General.pm (backname): New.
10384 2001-10-24 Akim Demaille <akim@epita.fr>
10386 * m4/: Remove, merged into...
10387 * config/: here.
10389 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10391 * doc/autoconf.texi (Shellology): Mention the problems with bash
10392 2.05's use of ANSI quoting in its `set' builtin.
10394 2001-10-22 Paul Eggert <eggert@twinsun.com>
10396 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10397 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10398 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10399 POSIX decided to standardize on the int flavor of strerror_r.
10400 Always do char* test, as there's no reason not to.
10401 Assign to a char* var, to catch strerror_r that returns int*.
10403 * doc/autoconf.texi (Particular Functions):
10404 Document the above changes. Also, document the fact that
10405 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10407 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10409 2001-10-20 Akim Demaille <akim@epita.fr>
10411 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10412 the executable was missing from the log.

10416 * lib/Autom4te/General.pm (&update_file): If destination is
10417 unchanged, remove the source.
10418 (&up_to_date_p): Don't be verbose, be debug.
10419 * bin/autoreconf.in: No longer support --m4dir.
10420 (&autoreconf): Display the full path of the configure.ac we are
10421 studying.
10422 Trace it only once.
10423 Be sure to honor --force with gettextize.
10424 Always run aclocal.
10425 * doc/autoconf.texi: Adjust.
10427 2001-10-20 Akim Demaille <akim@epita.fr>
10429 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10430 Remove, dead.
10431 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10432 `intl' is already present, as it refuses unless --force.
10433 (&parse_args): Use -I, --include instead of the old Autoconf
10434 options.
10435 ($localdir, $autoconf_dir): Remove.
10436 (@include): New.
10437 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10439 2001-10-19 Jens Petersen <petersen@redhat.com>

10447 file in @configure_input@.
10448 Don't mention `automatically' in addition to `generated'.
10449 * tests/torture.at (#define header templates): Adjust.
10451 2001-10-19 Akim Demaille <akim@epita.fr>
10453 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10454 comment, explain how to install automatic mode selection.
10455 From Russ Allbery.
10457 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10459 * bin/autoreconf.in (autoreconf): Display the path to the
10460 configure.ac being studied.
10462 2001-10-18 Paul Eggert <eggert@twinsun.com>
10464 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10465 long, to work around a bug in the HP C compiler version HP92453-01
10466 B.11.11.23709.GP.
10468 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10469 (AS_BASENAME_EXPR): New macro.
10470 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10471 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10472 and fall back on 'sed' only if the other two fail. This makes
10473 AS_BASENAME act more like AS_DIRNAME.
10474 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10475 contains white space.
10476 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10477 Use AS_DIRNAME, since I think it's now DOS-friendly.
10478 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10479 Allow "dirname //FOO" to return either / or //, as POSIX allows
10480 either behavior.
10482 2001-10-10 Akim Demaille <akim@epita.fr>
10484 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10486 From Eric Sharkey.

10490 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

10609 * tests/tools.at (AT_DATA_FORBIDDEN): New.

10620 empty, and if we can find a shell that does support LINENO,
10621 then set CONFIG_SHELL to that shell and then re-execute
10622 ourselves with CONFIG_SHELL.
10624 2001-10-05 Paul Eggert <eggert@twinsun.com>
10626 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10627 doesn't exist. Remove *.tmp, as a .tmp file is created during the

10630 2001-10-05 Akim Demaille <akim@epita.fr>
10632 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

10662 2001-10-02 Paul Eggert <eggert@twinsun.com>
10664 * doc/autoconf.texi (Limitations of Builtins): You can't use
10665 "source"; it's not portable. Remove confusing and
10666 somewhat-incorrect example involving "." and "/".
10668 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
10669 compatibility with POSIX shells.
10671 2001-10-02 Akim Demaille <akim@epita.fr>
10673 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
10674 instead of exec'ing to preserve $0 and $@.
10676 2001-10-01 Akim Demaille <akim@epita.fr>
10678 * tests/testsuite (AT_INIT) <at_pass_list>: New.

10681 2001-10-01 Akim Demaille <akim@epita.fr>
10683 * lib/autotest/general.m4 (AT_INIT) <--help>: Catch up with reality.
10684 No longer output the list of tests.
10685 <--list>: New option.
10686 <--full-help>: Remove.
10687 Complete the short/long options duality.
10688 Various small adjustments.
10690 2001-10-01 Akim Demaille <akim@epita.fr>
10692 * doc/autoconf.texi: Use @kbd for user input.

10697 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10698 Don't use nested parenthesization. This patch was originally
10699 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
10700 but somehow it didn't get incorporated then.
10701 * doc/autoconf.texi (Limitations of Usual Tools):
10702 Clarify remark about sed and nested parenthesization.
10704 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
10705 Report an error if the size cannot be determined even though
10706 the type exists.
10707 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10708 Check for `expr' arithmetic overflow, and for compilation failure,
10709 and invoke a new argument $4 if either is discovered.
10710 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10711 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10713 2001-09-28 Akim Demaille <akim@epita.fr>

10721 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
10722 (AT_TESTED): this.
10723 (AT_INIT): More the wrapped section to where it will be expanded.
10724 Output `AT_tested' only when existing.
10725 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
10727 2001-09-27 Akim Demaille <akim@epita.fr>
10729 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
10730 generates too many bug reports.
10732 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
10733 status when executing the ACTION-IF-FALSE.
10734 * tests/base.at (AC_TRY_*): Rename as...

10740 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
10741 * tests/c.at (Extensions, C keywords)
10742 (Broken/missing compilers, AC_PROG_CPP with warnings)
10743 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10744 (AC_PROG_CPP requires AC_PROG_CC): here and...
10745 * tests/fortran.at (GNU Fortran 77): there.
10746 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10747 AC_TRY_RUN is about compilation, not shell commands.
10748 (Test Programs): AC_TRY_RUN works as used to be advertised.
10750 2001-09-27 Akim Demaille <akim@epita.fr>
10752 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10753 Raja R Harinath:
10754 Be sure to detect when $LINENO always returns the same value.
10755 Look for the original script, basename($0) is certainly not
10756 enough.
10757 Pass the CLI arguments to `$as_me.lineno'.
10759 2001-09-25 Akim Demaille <akim@epita.fr>
10761 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

10769 of --language now.
10771 2001-09-23 Akim Demaille <akim@epita.fr>
10773 * doc/autoconf.texi (Top): Wrap in @ifnottex.
10775 2001-09-23 Akim Demaille <akim@epita.fr>
10777 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
10778 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10779 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10780 builddir, buildpath, top_builddir, and top_buildpath.
10781 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10782 the current directory.
10783 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
10784 variables *before* changing the current directory.

10787 variables.
10789 * lib/autotest/general.m4: Do not reset AT_victims.
10790 Don't compute at_srcdir nor at_top_srcdir.
10792 * tests/tools.at: Hence use top_srcdir.
10794 * tests/Makefile.am, tests/autoconf, tests/autoheader,
10795 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10796 Remove.
10797 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
10798 * tests/wrapsh.in, tests/autoupdate.in: New.
10799 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10800 * configure.ac: Build the position independent wrappers.
10802 * man/Makefile.am: Now that test wrappers are position
10803 independent, use them and drop dark envvar magic.
10805 2001-09-23 Akim Demaille <akim@epita.fr>
10807 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10808 (Programming in M4sh): this.
10809 Promote to @section.

10826 over-escaping.

10836 (Autoconf): Adjust.
10838 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
10840 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

10851 * lib/autoconf/autotest.m4: Create `package.m4'.
10852 * tests/Makefile.am (package.m4): Remove.
10854 2001-09-22 Akim Demaille <akim@epita.fr>
10856 Rely on `$LINENO' when possible instead of `__oline__'.
10858 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10859 `$LINENO' support replacement when not supported.
10860 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10861 them explicitly to be sure they are not output before this section
10862 (via m4_require). Cosmetic only.
10863 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10864 * lib/autoconf/programs.m4: Replace all the occurrences of
10865 `__oline__' with `$LINENO'.

10868 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10870 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10871 character (u: -> ue) in a code comment.
10872 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10873 it works.
10875 2001-09-21 Akim Demaille <akim@epita.fr>
10877 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10878 Suggested by Jim Meyering.
10880 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10882 * lib/autoconf/programs.m4: Use extensions listed in
10883 $ac_executable_extensions when looking for programs.
10885 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10887 * lib/autoconf/general.m4: Fix a small Englisho.
10888 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10889 setting up ac_dir_suffix and ac_top_builddir.
10890 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10892 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10894 * doc/autoconf.texi (File System Conventions): Clarify the use of
10895 PATH_SEPARATOR.
10896 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10897 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10898 be used instead of ':'.
10899 * lib/autotest/general.m4: Replace occurrences of ':' in
10900 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10902 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10904 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10905 arguments. Fixed a typo.
10907 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10909 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10910 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10912 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10914 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10915 * bin/autoupdate.in: Ditto.
10916 * bin/autoheader.in: Reworded a few comments.
10917 * bin/autoconf.in: Reworded help text for a few options.
10918 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10919 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10921 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10923 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10924 already have $file). Set output files to binary mode (helps avoid
10925 CR issues on DOSish systems).
10927 2001-09-19 Akim Demaille <akim@epita.fr>
10929 * lib/autotest/general.m4: Englishoes.
10930 From Tim Van Holder and Alexey Mahotkin.
10932 2001-09-18 Paul Eggert <eggert@twinsun.com>
10934 * doc/autoconf.texi (Common Shell Constructs): New node,
10935 documenting AS_DIRNAME.
10936 (Limitations of Usual Tools): Refer to it when discussing dirname.
10937 Also, update discussion of POSIX standard to reflect latest draft.
10939 * lib/autoconf/c.m4:
10940 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10942 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10943 Do not pass a first argument with leading '-'
10944 to expr, by parenthesizing initial integers that might be negative.
10946 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10947 now merely checks whether it is an error to pass an argument
10948 to getpgrp.
10950 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10951 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10952 whether it is a (compile-time) error to pass an argument to
10953 getpgrp. This simpler test supports the revised documentation,
10954 and is all that AC_FUNC_GETPGRP's users really need.
10956 2001-09-18 Akim Demaille <akim@epita.fr>
10958 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10960 2001-09-18 Akim Demaille <akim@epita.fr>

10966 2001-09-18 Paul Wagland <paul@wagland.net>
10968 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10969 correctly.
10970 Add test for AS_BASENAME.
10971 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10972 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10973 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10974 * tests/base.at: Fixed the expected responses. The old ones were
10975 one line out...
10976 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10977 the documentation claims it should (and how it behaved in 2.13).
10979 2001-09-18 Akim Demaille <akim@epita.fr>
10981 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10982 the AC_CONFIG_COMMANDS invocation.
10983 This also solves the name clash problems.
10984 Don't set the package's ID.
10985 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10986 No longer to be shipped.
10987 (version.in): Remove.
10988 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10989 * lib/autoconf/status.m4: Adjust.
10990 Use `m4_PACKAGE_STRING'.
10991 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10992 the only optional argument is the name of the test suite.
10993 Expect `package.m4' to define the package signature.
10994 * lib/autom4te.in (Autotest): Add `package.m4?'.
10995 * tests/Makefile.am (package.m4): New.
10996 * tests/suite.at: ifnames is a victim.
10998 2001-09-18 Akim Demaille <akim@epita.fr>
11000 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11001 AC_LIBSOURCE, AC_CONFIG_FILES.
11002 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11003 program version string doesn't match the package's.
11004 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11005 after `(cached)'.
11007 2001-09-17 Paul Eggert <eggert@twinsun.com>
11009 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11010 Allow expression to return any value that can fit into unsigned long
11011 (not int, as before). Check for output errors.
11013 2001-09-17 Bruno Haible <haible@ilog.fr>
11015 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11016 Always include <stdio.h> and <stdlib.h>. Evaluate
11017 the expression in an extra function before these includes. Call
11018 fprintf "%d" only after ensuring the argument is of type 'int'.
11019 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11021 2001-09-17 Paul Eggert <eggert@twinsun.com>
11023 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11024 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11025 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11026 when they don't exist.
11028 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11029 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11030 need it.
11032 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11033 version with the version used by fileutils 4.1, except use
11034 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11035 we don't need it.
11037 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11039 2001-09-13 Akim Demaille <akim@epita.fr>
11041 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11042 _first_.
11043 Reported by Gerrit P. Haase.
11045 2001-09-13 Akim Demaille <akim@epita.fr>
11047 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
11048 m4_defn'ing is valid.
11050 2001-09-13 Akim Demaille <akim@epita.fr>
11052 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
11053 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
11054 Use it.
11056 2001-09-13 Akim Demaille <akim@epita.fr>
11058 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
11059 m4_match.
11060 (m4_re_escape): New.
11061 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
11062 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
11063 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11064 Likewise.
11065 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
11066 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
11067 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11068 AT_tests_all for consistency.
11069 Set at_victims.
11070 (AT_VICTIMS): Similar to AT_KEYWORDS.
11071 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11073 2001-09-13 Akim Demaille <akim@epita.fr>
11075 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11077 2001-09-13 Akim Demaille <akim@epita.fr>
11079 * lib/autotest/general.m4 (AT_INIT): Create and remove
11080 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11081 test suites can cohabit.
11083 2001-09-13 Akim Demaille <akim@epita.fr>
11085 * tests/mktests.sh: Don't output banners for empty test files.
11087 2001-09-13 Akim Demaille <akim@epita.fr>
11089 Test suites can be run independently of configure.
11091 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
11092 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.
11093 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust: AC_SUBST

11099 2001-09-13 Akim Demaille <akim@epita.fr>
11101 * bin/ifnames.in: Rewrite in Perl.
11102 * configure.ac: Don't look for AWK.
11103 * tests/tools.at (AWK portability): Remove.
11104 (Syntax of the shell scripts): Don't check ifnames.
11105 (AT_CHECK_PERL_SYNTAX): New.
11106 (Syntax of the Perl scripts): Check ifnames.
11107 * tests/ifnames: New.
11109 2001-09-13 Akim Demaille <akim@epita.fr>

11153 2001-09-07 Akim Demaille <akim@epita.fr>
11155 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11156 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11157 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11158 related variables into `at_package_*'.

11170 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
11171 in addition, it introduces useless differences in logs.

11173 Adjust PATH computation.
11174 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

11189 * bin/autom4te.in: --language is -l, not -s.
11191 2001-09-05 Akim Demaille <akim@epita.fr>
11193 Be ready to handle filenames as stupid as `dnl.at', for if even
11194 the maintainer is dumb enough to do that...
11196 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11197 excellence in M4 quotation: consider `__file__' is active.
11199 And BTW, when invoking m4, pass the --include in the right order:
11200 the wrong one.
11202 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11203 4m.
11205 2001-09-05 Akim Demaille <akim@epita.fr>
11207 * lib/Autom4te/XFile.pm: New lib file.
11208 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
11209 * bin/autoheader.in: Use it.
11211 2001-09-05 Akim Demaille <akim@epita.fr>
11213 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

11225 2001-09-05 Akim Demaille <akim@epita.fr>
11227 CVS GNU M4 doesn't like `undefine(undefined)'.
11229 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11230 New, extracted from main.
11231 Use IO::File wherever possible.
11232 (input.m4): Be constant, use -I instead of hard coding $tmp.
11233 Therefore be a quoted heredoc.
11234 Don't invoke `_au_disable', since ac was not loaded, but just
11235 `unm4.m4'.
11237 2001-08-31 Akim Demaille <akim@epita.fr>
11239 Version 2.52d.
11241 2001-08-31 Akim Demaille <akim@epita.fr>

11244 previous patch.

11251 Reported by Nicolas Joly.
11253 2001-08-31 Akim Demaille <akim@epita.fr>
11255 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.

11260 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11262 2001-08-31 Akim Demaille <akim@epita.fr>
11264 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11265 (testsuite Scripts): There is no such thing as `atconfig.in'.
11266 And actually one diagram is missing: test suite runtime.
11268 2001-08-31 Akim Demaille <akim@epita.fr>
11270 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11271 inverse order.
11273 2001-08-31 Akim Demaille <akim@epita.fr>
11275 * bin/autoupdate.in (@include): `installcheck' revealed the path
11276 to m4sugar was lacking!
11278 2001-08-31 Akim Demaille <akim@epita.fr>
11280 * man/Makefile.am (.x.1): We really have to pass
11281 autom4te_perllibdir.
11283 2001-08-31 Akim Demaille <akim@epita.fr>
11285 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11286 debug scripts, in particular passing explicitly listed tests to
11287 run is stupid.
11289 2001-08-31 Akim Demaille <akim@epita.fr>
11291 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11292 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11293 Use directly autom4te, not autoconf.
11294 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11296 2001-08-31 Akim Demaille <akim@epita.fr>
11298 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11299 * bin/autoheader.in (%symbol): Strip arguments of macros.

11307 * bin/autom4te.in (&parse_args): Die on unknown languages.
11308 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11309 need for autoconf.
11310 Promote --include over --macrodir and other obsolete options.
11312 2001-08-31 Akim Demaille <akim@epita.fr>
11314 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

11316 * bin/autom4te.in ($autoconf): Pass --force.
11317 `print $out' doesn't print `$_' but `$out'.
11318 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11319 (autoheader): Pass --force since the test suite goes too fast for
11320 the time stamps.
11321 Adjust to the new autoheader messages.
11323 2001-08-31 Akim Demaille <akim@epita.fr>
11325 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11326 Check the completeness of the #template.
11327 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11328 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER

11334 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11335 Drop AC_MACRODIR dead for real.
11336 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11337 `autoheader: `config.hin' is created'.
11338 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11340 2001-08-31 Akim Demaille <akim@epita.fr>
11342 * bin/autoheader.in: Rewrite in Perl.
11343 * tests/autoheader: Adjust.
11345 2001-08-31 Akim Demaille <akim@epita.fr>
11347 * bin/autoconf.in (--include, -I): New option.
11348 Map --localdir, --autoconf-dir onto it.
11349 Forward autom4te's options instead of interpreting them.
11350 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11351 There is no such envvar since the inception of autom4te.cfg.
11352 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11353 * bin/autoupdate.in: Adjust, and perform more control.
11354 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11355 * tests/autoconf: Dittowise.
11357 2001-08-31 Akim Demaille <akim@epita.fr>
11359 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11360 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11361 optionally `FILE'.
11362 Use -e, not -f, since /dev/null for instance is OK.
11363 (&parse_args): Adjust.
11364 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11366 2001-08-31 Akim Demaille <akim@epita.fr>
11368 * configure.ac: Also find tested executables in bin.
11369 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11370 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11371 installed peer executables, only PATH is allowed to resolve it.
11372 Pass `autoconf_dir' via options, not via invisible envvars.
11373 * lib/Autom4te/General.pm (&find_peer): Remove.
11374 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11375 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11376 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11377 find the executables for it.
11378 * tests/Makefile.am: Major cleanup. Too lazy to document...
11379 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11380 We only need PERL.
11381 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11382 indeed related to running the test suite, while passing
11383 --autoconf-dir and others is related to running non installed
11384 Autoconf executables. So don't do that, leave it to...
11385 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11386 * tests/autoscan: New.
11387 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11388 refer to library files: rely on --language.
11390 2001-08-29 Akim Demaille <akim@epita.fr>
11392 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11393 s/--set/--language/.
11395 2001-08-29 Akim Demaille <akim@epita.fr>
11397 * doc/autoconf.texi: Strip the @nodes.
11398 Suggested by Paul Eggert.
11399 (Initializing configure): Typo.
11401 2001-08-29 Akim Demaille <akim@epita.fr>
11403 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11404 Suggested by Paul Eggert.
11406 2001-08-29 Akim Demaille <akim@epita.fr>
11408 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11409 download in a tmp dir.
11411 2001-08-29 Akim Demaille <akim@epita.fr>
11413 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11414 case insensitive OSes out there :(

11424 (&parse_args): Support --mode, --set, and --melt.
11425 * bin/autoconf.in: Simplify and adjust.
11426 * tests/Makefile.am (AUTOMAKE): Use --set.
11427 * tests/atlocal.in: Adjust.
11428 * BUGS: distcheck and check are weak.
11430 2001-08-29 Akim Demaille <akim@epita.fr>
11432 * lib/autotest/general.m4: Use
11433 foo=`(command) 2>/dev/null`
11434 not
11435 foo=`command` 2>/dev/null
11436 (at-devnull): Rename as...
11437 (AT-devnull): this.
11438 (--clean): Remove AT-* files too.
11439 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11440 Reported by Nicolas Joly.

11474 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11475 Support `VAR=VAL' as arguments.

11495 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11496 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11497 readable.
11498 Adjust callers.
11499 * doc/autoconf.texi (Configuration Actions): Document the vars
11500 available in commands.
11501 Emphasize the risks of collisions in init-cmds.

11564 (AMTAR): Help automake define it.
11565 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11566 needed, 1.5 can have a macro and a target with the same name.
11567 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11568 * m4/strip.m4: New.
11569 * m4/init.m4, m4/sanity.m4: Update.

11583 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11584 the name of the directory they're in, instead of the filename,
11585 since version.m4 is now in m4sugar, but m4_acversion must not be
11586 classified as an Autoconf macro.
11587 ($input_m4): Don't qualify the path to m4sugar.
11588 Rather, pass autoconf_dir to m4.
11589 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11677 2001-08-20 Akim Demaille <akim@epita.fr>
11679 Info readers seem to need `Index' in the index node title :(
11681 * doc/autoconf.texi: Reverse the 2001-08-15 change which

11726 2001-08-20 Akim Demaille <akim@epita.fr>
11728 Huh!?!?! There are still some user EOF tags used, which prevents

11731 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11732 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

11795 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

11811 2001-08-17 Akim Demaille <akim@epita.fr>
11813 * doc/autoconf.texi: Work around Texinfo buglets.
11814 (Transformation Rules): One example is enough, users are expected
11815 to have their brains on. And BTW, use DESTDIR.
11816 (dvar): New macro. Use it.
11818 2001-08-17 Akim Demaille <akim@epita.fr>
11820 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11868 (cvs-dist): depends upon it.
11870 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11872 * tests/Makefile.am: Use a clean-local rule to remove
11873 autom4te.cache (it's a directory, not a file.
11874 * Makefile.am: Ditto (but maintainer-clean-local).
11876 2001-08-15 Akim Demaille <akim@epita.fr>
11878 * bin/autom4te.in (@m4_warning): New.
11879 (&handle_m4): Use it.
11880 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11881 warnings are issued at each run.
11882 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11883 is in the src tree.
11885 2001-08-15 Akim Demaille <akim@epita.fr>

11888 don't waste time running `autoupdate --version' works.

11944 * tests/mktests.sh: Update year in copyright notice.
11946 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11948 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11950 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11952 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11953 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11954 * doc/autoconf.texi (C Compiler Characteristics): Update
11955 documentation for AC_C_BIGENDIAN.
11957 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11959 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11960 magic values from an object file when cross-compiling.
11961 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11963 2001-08-10 Akim Demaille <akim@epita.fr>
11965 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11966 effects.
11967 Suggested by Russ Allbery.
11969 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11971 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11972 current $prefix to the sub-configures.
11974 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11976 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11977 extension (needed on BeOS). Reported by Guido van Rossum.
11979 2001-08-09 Akim Demaille <akim@epita.fr>
11981 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11983 2001-08-07 Akim Demaille <akim@epita.fr>
11985 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11986 removed.
11987 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11988 No need to remove the files before and after the each test, before
11989 each test and at the end of the suite is enough.
11990 Display only the children `times', not the shell's.
11991 If the test failed or was skipped, at-times is not available.
11993 2001-08-07 Akim Demaille <akim@epita.fr>
11995 Always produce testsuite.log, including when there are no
11996 failures. This helps getting information on skipped tests, and
11997 duration of the tests. Err, implement the latter btw.
11999 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12000 Dump information on the first run of each test.
12001 (AT_CLEANUP): Create `at-times' containing the duration of the
12002 test group.
12004 2001-08-07 Akim Demaille <akim@epita.fr>
12006 The use of `dumpstat' revealed that `len' was used although it
12007 should not. m4_text_wrap was using it, but in the Autoconf world
12008 where it is legal. Hence (i) test M4sh in its own world, not
12009 Autoconf's, and (ii), ahem, fix the bug :)
12011 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12012 does not like `' instead of [].
12013 (AT_INIT): Forbid `^_?AT_'.
12014 And don't output such tokens.
12015 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',

12019 * tests/m4sugar.at: Use it.

12039 2001-08-04 Akim Demaille <akim@epita.fr>
12041 Don't rely on M4sugar outputting the patterns in files, since we
12042 might process the output _without_ running m4, hence without these
12043 files.

12046 * bin/autom4te.in (@Request::includes): Remove, unused.

12055 2001-08-04 Akim Demaille <akim@epita.fr>
12057 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&

12078 Don't let autom4te compute the `include' traces several times:
12079 first check that the trace cache file is up to date, and then
12080 compare its timestamp with that of the output.
12082 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12083 the preamble. Don't require 5.005 as Autom4te::General does it,
12084 and better yet (use `use', not `require'!).
12085 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12086 Class::Struct as Autom4te::Struct.
12087 * lib/Autom4te/General.pm (File::stat): Use it.
12088 (&mtime): New, export it.
12089 * bin/autom4te.in: Use it.
12090 Declare `$req' is invalid if it is outdated.

12112 * bin/autom4te.in (handle_traces): Fix rewriting of traces without

12607 provide an alternate 'main' function name, using the 'main' from
12608 the Fortran libraries.
12609 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12610 cross-language link tests can be performed successfully.
12611 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12612 after $LIBS, for consistency; this should be the general rule since
