(AS_INIT): Push the BODY diversion, set the #! /bin/sh line.
* lib/autoconf/general.m4 (AC_PLAIN_SCRIPT) : Remove.
(AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
include handle the m4_pattern_*, no longer push the
BODY diversion nor set the /bin/sh line, AS_INIT does it.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* tests/base.at: Adjust the tests to use AS_INIT.
* tests/tools.at (AT_DATA_FORBIDDEN): New.
(autoconf: forbidden tokens): Adjust to work on M4sh instead of
Autoconf.
and if CONFIG_SHELL is unset or empty, and if we can find a shell that
does support LINENO, then set CONFIG_SHELL to that shell and then
re-execute ourselves with CONFIG_SHELL.
* lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Be sure to set
PATH_SEPARATOR before using it.
Fix the absolute path case/esac pattern.
Provide $0 as fallback for as_myself.
Reported by Raja R Harinath.
Don't use nested parenthesization. This patch was originally
suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
but somehow it didn't get incorporated then.
Check for `expr' arithmetic overflow, and for compilation failure,
and invoke a new argument $4 if either is discovered.
This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
(_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
(AT_TESTED): this.
(AT_INIT): More the wrapped section to where it will be expanded.
Output `AT_tested' only when existing.
Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
generates too many bug reports.
* lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
status when executing the ACTION-IF-FALSE.
* tests/base.at (AC_TRY_*): Rename as...
(AC_TRY_COMMAND): this.
(AC_RUN_IFELSE): New.

(AC_PROG_CPP requires AC_PROG_CC, GNU Fortran 77)
(Broken/missing compilers, AC_PROG_CPP with warnings)

* tests/c.at (Extensions, C keywords)
(Broken/missing compilers, AC_PROG_CPP with warnings)
(AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
(AC_PROG_CPP requires AC_PROG_CC): here and...
* tests/fortran.at (GNU Fortran 77): there.
* doc/autoconf.texi (autoconf Invocation): Fix the example:
AC_TRY_RUN is about compilation, not shell commands.
(Test Programs): AC_TRY_RUN works as used to be advertised.
Raja R Harinath:
Be sure to detect when $LINENO always returns the same value.
Look for the original script, basename($0) is certainly not
enough.
Pass the CLI arguments to `$as_me.lineno'.
ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
(_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
builddir, buildpath, top_builddir, and top_buildpath.
(_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
the current directory.
* lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
variables *before* changing the current directory.
Skip nonexistent dirs.
* doc/autoconf.texi (Preset Output Variables): Document these
variables.
* lib/autotest/general.m4: Do not reset AT_victims.
Don't compute at_srcdir nor at_top_srcdir.
* tests/tools.at: Hence use top_srcdir.
* tests/Makefile.am, tests/autoconf, tests/autoheader,
* 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.
* configure.ac: Build the position independent wrappers.
* man/Makefile.am: Now that test wrappers are position
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.
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.
(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/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)'.
Allow expression to return any value that can fit into unsigned long
(not int, as before). Check for output errors.
From Bruno Haible: 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>.
