Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
Don't use the term "thread-safe" to talk about mkdir race
conditions, since the problem is more a process than a thread
issue. Problem reported by Stepan Kasal in:
http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
the test for 'install' more closely. Look at MKDIR_P first.
Look in the PATH, and at /opt/sfw/bin.
Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
Don't bother to try mkdir -p, since we already check mkdir --version;
just look at the version number. (There's no easy way to check
for race-free implementations.)
* tests/tools.at (autoconf: subdirectories): Adjust to above
changes, since MKDIR_P now might end in "/mkdir -p".
AC_DEFINE is now passed to m4_pattern_allow.
* NEWS: Mention that; likewise for AC_SUBST.
* lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
the parameter to m4_pattern_allow.
* tests/tools.at: Add a check for that.
some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
Instead, just list the shells that we know work.
* tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
changed. Be more cautious about the _cv_ variable.
* tests/tools.at (Syntax of the shell scripts): Check the
_cv_ variable once, at first, to avoid an internal autoconf error
when sh -n does not work.
distinguish m4sugar macros.
* tests/tools.at (autoupdating with aclocal and m4_include):
New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
test case by Noah Misch <noah@cs.caltech.edu>.
macros without parameters.
* lib/autoconf/autoupdate.m4 (AU_ALIAS): Likewise.
* doc/autoconf.texi (Obsoleting Macros): Document AU_ALIAS.
* tests/tools.at (autoupdating AU_ALIAS): New test for AU_ALIAS
`$#' bug.
(autoupdate): Updated to match AU_ALIAS fix.
The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
and CONFIG_COMMANDS are not processed in four separate loops.
Instead, there is one main loop. This alows that the common code
is expanded only once, thus config.status (and configure) is smaller.
The registration mechnism in AC_CONFIG_FILES and cousins also changed;
the AC_LIST_FILES and cousins macros are no longer used.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
(_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
_AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
contains the initialization, nor the for loop, nor the associated
commands; all these go to ...
(_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
_AC_OUTPUT_CONFIG_STATUS.
(_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
(_AC_OUTPUT_FILE): The creation of the sed script ...
(AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
(_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
_AC_OUTPUT_MAIN_LOOP.
(_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
_AC_CONFIG_COMMANDS): Use ...
(_AC_CONFIG_FOOS): ... this new macro, which uses these ...
(_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
(_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
_AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
(_AC_CONFIG_DEPENDENCY): Update, it uses these ...
(_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
... new macros.
(_AC_CONFIG_UNIQUE): Update.
(AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
Replaced by this ...
(_AC_LIST_TAGS): ... new common macro.
(AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
AC_LIST_COMMAND_COMMANDS): Replaced by this ...
(_AC_LIST_TAG_COMMANDS): ... new common macro.
(_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
this didn't belong to the `config commands' section.
(_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
(AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
to the `config commands' section either.
(AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
(_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
... and many changes to the comments nearby.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
set ac_subdirs_all='_AC_LIST_SUBDIRS'.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
(#define header templates): The comment at the top of the generated
header now includes the name(s) of the source file(s).
Several unrelated small changes:
* lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
parameter to AC_DIAGNOSE.
* lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
(_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
(AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
with AU::AC_OUTPUT.
(AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
in AC_OUTPUT doesn't double-quote it either.
* tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
parameters.
* doc/autoconf.texi: Don't say that the third parameter
is broken.
* lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.

of autoupdate.
* configure.ac: Test if sh -n works.
* configure: Regenerate.
* tests/atlocal.in: Store the result here.
* tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
tools.at, looking in atlocal's ac_cv_sh_n_works instead
of explicitly testing.

(AT_CHECK_AUTOCONF): Test for the configure script syntax.
* tests/tools.at (Syntax of the shell scripts): Simplify
using AT_CHECK_SHELL_SYNTAX.

63 for version mismatches.

`@', to tickle Perl's lists.
Reported by Carlos Velasco.
longer required can still cause errors.
Reported by Alexandre Duret-Lutz.
* bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
to frozen files in @ARGV, as @ARGV must remain being a list of
files. Rather, at M4 call sites, use this...

(&freeze): Use &error.
