(alpha beta major): Add changelog-check. Check version.
* configure.ac (AC_CONFIG_AUX_DIR): Renamed from config to build-aux.
(AC_CONFIG_FILES): Remove.

* config/announce-gen: Sync from coreutils.
* doc/make-stds.texi: Sync from gnulib.
* doc/standards.texi: Likewise.
* man/Makefile.am: Adjust for config -> build-aux renaming.
* tests/Makefile.am: Prefer $(FOO) to @FOO@.
* tests/local.at: Adjust from config -> build-aux renaming.
* tests/tools.at: Likewise.
* tests/torture.at: Likewise.
calls, so that we do not care whether they are LIFO or FIFO;
in the m4_wrap, do not check which diversion is the topmost
one, just check that the stack is balanced at the end.
* lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
base diversion forever--pop the previous diversion before
opening the new one; consequently, remove the m4_wrap call.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* tests/m4sugar.at: Do not use
m4_wrap([m4_diversion_pop([..])]), for educational purposes.
message issued by AC_REQUIRE.
* tests/m4sugar.at: Check m4_require's error message.
* tests/base.at: Check AC_REQUIRE's error message.
* tests/local.at (AT_CHECK_M4): New macro, almost identical
to...
(AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
AT_CHECK_M4.
(AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
`expout' as the last parameter.
* tests/tools.at: Adapt to the above change.
* doc/autoconf.texi (Special Chars in Variables): New section.
(Preset Output Variables): Warn about special chars in CPPFLAGS.
(Installation Directory Variables): Quote $(datadir) better.
(Limitations of Builtins): Describe some of eval's trickiness.
* lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
* lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
in front of every arg, not just trailing args. Quote apostrophes.
(_AC_EVAL_ECHO): New macro.
(_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
(AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
removed.
(_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
exposed by quoting of eval argument. Put the command on line line
so it logs better.
* lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
(_AC_PATH_X, AC_PATH_X): Quote more safely.
* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
* lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
Handle special chars in prefix, ac_srcdir, ac_aux_dir.
Use eval more safely.

* lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
to be replaced.

lines, exposed by quoting of eval argument.
sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
Warn about obsolete install-sh files. Remove stray sentence
fragment and fix cross reference.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
install -d; this undoes the 2006-05-10 change.
(MKDIR_P): Mark with AN_MAKEVAR.
(AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
that we don't require $INSTALL to be thread-safe. Move comments
out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
of AC_PROG_INSTALL. Output a message saying that we're checking
mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
MKDIR_P instead of AC_SUBST.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
Special magic for MKDIR_P, too.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
a dnl.
* tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
* config/install-sh: Don't use 'path' to talk about file names,
as per GNU coding standards. Close a race condition reported by Ralf
Wildenhues and Stepan Kasal. There is still a race condition
on hosts that predate POSIX 1003.1-1992, but we can't help this.
Don't mishandle weird characters like space on pre-POSIX hosts.
Invoke mkdir at most once per dir arg on pre-POSIX hosts.
* doc/autoconf.texi (Programming in M4sh): Cross-reference to
AC_PROG_MKDIR_P from AS_MKDIR_P.
(Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
from mkdir. Mention that Autoconf 2.60 install-sh is safe but
earlier editions are not (including Automake 1.8.3).
Do not suggest mkinstalldirs for thread-safety.
* lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
presence of special characters and race conditions.
* tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
in Autoconf's name space.
* lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
from Automake with minor changes.
* doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
* doc/autoconf.texi (Programming in M4sh): Comment out the
documentation of AS_BASENAME, for now.
(Shell Substitutions): Do not use AS_DIRNAME in an example.
(Limitations of Builtins) <basename>: Do not refer to
AS_BASENAME.
* bin/autoconf.as (me): Don't use AS_BASENAME.
(dir): Remove the unused variable.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
(AS_BASENAME): Use "basename --" to protect against leading "-".
(_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
(_AS_DIRNAME_PREPARE): Likewise.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
(AS_DIRNAME): Use "dirname --".
and AS_BASENAME.
* lib/m4sugar/m4sh.m4 (AS_BASENAME, AS_DIRNAME): Bring these
back, albeit undocumented. Programs now have a grace period
to switch to AS_VAR_SET_DIRNAME and AS_VAR_SET_BASENAME.
AS_VAR_SET_DIRNAME and AS_VAR_SET_BASENAME.
* doc/autoconf.texi (Programming in M4sh): Document this. All uses
changed. The newer interfaces are more reliable, as they allow
implementations that handle trailing newline correctly. For now,
we're in a freeze, so I did not include the more-reliable
implementations, but I wanted to correct the interface before 2.60
goes out.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
(_AS_BASENAME): Renamed from AS_BASENAME. All uses changed.
Use "basename --" to protect against leading "-".
(_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
(_AS_DIRNAME_PREPARE): Likewise.
(_AS_DIRNAME): Renamed from AS_DIRNAME. All uses changed.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
Use "dirname --".
(AS_VAR_SET_BASENAME, AS_VAR_SET_DIRNAME): New macros.
* tests/m4sh.at (AS_VAR_SET_DIRNAME): Renamed from AS_DIRNAME.
Test the new API. Don't test internals, since they're probably
going to change anyway.
(AS_VAR_SET_BASENAME): Likewise, renamed from AS_BASENAME.
* bin/autoconf.as: Don't use AS_BASENAME or AS_DIRNAME. This
removes a bootstrapping problem with the changes described above.
The AS_DIRNAME part wasn't used, anyway, and the AS_BASENAME
part can be done portably without all the deep Autoconf magic.
succeeded, but `ln -s file dir' failed, take care to remove the
leftover target before the next test, to prevent its spurious
failure; also make sure `ln file dir' works before selecting it.
Thanks to Keith Marshall for pointing this out.
* THANKS: Update.
with a target directory; it's internally implemented as `cp'
anyway, but since Autoconf advertises the possibility to use
a target directory when LN_S is `ln -s', we need to find out.

_AS_DETECT_BETTER_SHELL:
* lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
skip nonexistent directories.
(_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
only shell candidates which exist.
(AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
* lib/autotest/general.m4 (AT_INIT): No need to give three
parameters to _AS_PATH_WALK.
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
and DUALCASE=1.
(AS_SHELL_SANITIZE): Remove DUALCASE=1.
* doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
it is set.
