of rolling our own unset.
(_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
in practice we needn't worry about CDPATH if unset doesn't work.
Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
apparently treats PATH="nonexistent" as if it contained ".".
Bug reported by Stefan `Sec' Zehl.
workaround for ${1+"$@"}.
* doc/autoconf.texi (Shell Substitutions): Explain it.
From Oliver Kiddle and Peter Stephenson.
Have M4sh perform minimal shell sanitizing.
* lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
part into...
(_AS_PREPARE): this new macro.
(AS_PREPARE): New.
(AS_INIT): Invoke AS_SHELL_SANITIZE.
* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
Adjust Autoconf and Autotest.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
Invoke _AS_PREPARE (not AS_PREPARE) in addition to
AS_SHELL_SANITIZE.
Use this M4sh to generate Autoconf's shell scripts.
* tests/wrapsh.as: New, precursor of wrapsh.in.
* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
on Autotest and M4sh.
($(TESTSUITE)): Use $(autotest_m4f_dependencies).
(wrapsh.in): New target.
* bin/autoconf.as: New, precursor of autoconf.in.
(autoconf.in): New target.
(AS_MKDIR_P): Require it. Use mkdir -p if available, falling
back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does. That way, we need not have
our own filename disassembler. The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
work even if there are multiple instances of $LINENO on the same line.
Do not substitute for other variables like $LINENOT. Do not check
file dates; such a check is unreliable on sufficiently fast machines,
and removing the check makes the code simpler and more reliable.
Check for output and chmod failures.
(AS_BASENAME_EXPR): New macro.
(AS_BASENAME_SED): Do not assume GNU sed semantics.
(AS_BASENAME): Use 'basename' if that works; then try 'expr';
and fall back on 'sed' only if the other two fail. This makes
AS_BASENAME act more like AS_DIRNAME.
* lib/m4sugar/m4sh.m4: here.
(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.
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'.
* 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.
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).
m4_match.
(m4_re_escape): New.
* lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
* lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
* 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.
(AT_VICTIMS): Similar to AT_KEYWORDS.
(_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
PATH_SEPARATOR, let M4sh compute it.
* lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
* lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.
Move to...
* lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Here.
Simplify when the path is not a literal.
(AS_UNAME): Use it to report PATH.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE_FS_SEPARATORS): Remove.
(_AC_INIT_DEFAULTS): AC_SUBST PATH_SEPARATOR.
* lib/autoconf/programs.m4 (AC_PROG_INSTALL): Use _AS_PATH_WALK.
* lib/autotest/general.m4 (AT_INIT): Use _AS_PATH_WALK to
normalize the path, and to look for victims.
* tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
(AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
* lib/autotest/general.m4: Stop displaying srcdir everywhere as,
in addition, it introduces useless differences in logs.
(AT_INIT): Let atconfig and atlocal be both optional.
Adjust PATH computation.
* lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
* lib/autotest/autotest.m4: New.
* lib/autotest/general.m4, tests/atspecific.m4: Adjust.
* tests/suite.at : Adjust.

(_AC_INIT_PREPARE): Fix the incredibly messy and buggy completion
of config.log on traps.
(_AC_OUTPUT_CONFIG_STATUS): Use AS_BOX.
Use consistently `_ACEOF' for configure's here docs, and `_CSEOF'
for config.status'.
Open the log as soon as possible.
Use the same log introduction as configure's.
* autoconf.in ($automate): New var.
(task script): Use autom4te.

but some sed choke on multiple `;', and other tools (e.g.,
Automake), include the separator themselves.
* acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
