the current directory.

* tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
Remove.
* tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
* tests/wrapsh.in, tests/autoupdate.in: New.
* tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.

independent, use them and drop dark envvar magic.
Pass $at_debug_args to the rerun test suite.
* lib/m4sugar/Makefile.am (DISTCLEANFILES): New.
* bin/Makefile.am (ETAGS_SH): Don't use characters ranges.
From Paul Eggert.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
`$LINENO' support replacement when not supported.
(_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
them explicitly to be sure they are not output before this section
(via m4_require). Cosmetic only.
* lib/autoconf/c.m4, lib/autoconf/general.m4,
* lib/autoconf/programs.m4: Replace all the occurrences of
`__oline__' with `$LINENO'.
* doc/autoconf.texi (Special Shell Variables): Document LINENO.

setting up ac_dir_suffix and ac_top_builddir.
* lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
PATH_SEPARATOR.
(Special Shell Variables[PATH_SEPARATOR]): Ditto.
(Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
be used instead of ':'.
* lib/autotest/general.m4: Replace occurrences of ':' in
AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
* bin/autoupdate.in: Ditto.

New node, documenting AS_DIRNAME.
(Limitations of Usual Tools): Refer to it when discussing dirname.
Also, update discussion of POSIX standard to reflect latest draft.
(AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
* lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
Do not pass a first argument with leading '-'
to expr, by parenthesizing initial integers that might be negative.
now merely checks whether it is an error to pass an argument
to getpgrp.
* lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
(AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
whether it is a (compile-time) error to pass an argument to
getpgrp. This simpler test supports the revised documentation,
and is all that AC_FUNC_GETPGRP's users really need.

correctly.
Add test for AS_BASENAME.
* lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
added test. It now correctly handles /1/2/3/, returning '3' not ''.
Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
* tests/base.at: Fixed the expected responses. The old ones were
one line out...
* lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
the documentation claims it should (and how it behaved in 2.13).
the AC_CONFIG_COMMANDS invocation.
This also solves the name clash problems.
Don't set the package's ID.
* lib/m4sugar/Makefile.am (version.m4): Revamp.
No longer to be shipped.
(version.in): Remove.
* lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
* lib/autoconf/status.m4: Adjust.
Use `m4_PACKAGE_STRING'.
* lib/autotest/general.m4 (AT_INIT): N-th signature change: now
the only optional argument is the name of the test suite.
Expect `package.m4' to define the package signature.
* lib/autom4te.in (Autotest): Add `package.m4?'.
* tests/Makefile.am (package.m4): New.
* tests/suite.at: ifnames is a victim.
AC_LIBSOURCE, AC_CONFIG_FILES.
* lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
program version string doesn't match the package's.
* lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
after `(cached)'.

From Bruno Haible:
(AC_LANG_INT_SAVE(C)): Always include <stdio.h> and
<stdlib.h>. Evaluate the expression in an extra function before these
includes. Call fprintf "%d" only after ensuring the argument is of
type 'int'. Reported by Wayne Chapeskie <waynec@spinnaker.com>.

or CFLAGS=-O5. In that case, the linker has a relaxed view of
fatal errors, and AC_CHECK_LIB causes it to include libraries even
when they don't exist.
* lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
need it.
* lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
version with the version used by fileutils 4.1, except use
AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
we don't need it.
* doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
m4_match.
(m4_re_escape): New.
* lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.

* lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
Likewise.

(_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
* lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
AT_tests_all for consistency.
Set at_victims.
