* lib/autoconf/functions.m4, lib/autoconf/general.m4,
* lib/autoconf/headers.m4, lib/autoconf/libs.m4,
* lib/autoconf/programs.m4, lib/autoconf/specific.m4,
* lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
specify to what the macro should be defined (typically to 1).
AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
definition used by Automake where LEX is +/- "${missing} lex" and
`missing' itself contains variables.
(&file_name_is_absolute): New, wrappers around routines from
File::Spec.
Use and export them.
(&find_configure_ac): Optionally take a directory where to look at.
* bin/autoreconf.in (&parse_args): Trim the configure.ac part of
the arguments.
Default @ARGV to `.', not find_configure_ac.
(&autoreconf): Argument is a directory.
Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
* doc/autoconf.texi (autoreconf Invocation): Update.
(@export_forward_subs): New.
Add basename, dirname, and fileparse.
(@EXPORT): Adjust.
* bin/autoreconf.in (&autoreconf): Fix call to fileparse.
Don't look for aclocal flags if we already know aclocal is not
used.
Move aclocal.m4t only if it exists.

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.
ac_cv_func_strerror_r_char_p, and rename HAVE_WORKING_STRERROR_R to
STRERROR_R_CHAR_P, since POSIX decided to standardize on the int
flavor of strerror_r. Always do char* test, as there's no reason not
to. Assign to a char* var, to catch strerror_r that returns int*.
unchanged, remove the source.
(&up_to_date_p): Don't be verbose, be debug.
* bin/autoreconf.in: No longer support --m4dir.
(&autoreconf): Display the full path of the configure.ac we are
studying.
Trace it only once.
Be sure to honor --force with gettextize.
Always run aclocal.
* doc/autoconf.texi: Adjust.
(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.
(AC_INCLUDES_DEFAULT): Move to...
* lib/autoconf/headers.m4: here.
* lib/autoconf/types.m4: Comment changes.
* doc/autoconf.texi: Specify where the default includes are used
in the macro prototypes.
(&parse_args): Pass verbosity/debugging options to subtools when
--debug, not when --verbose.
* lib/autom4te.in (Autoreconf-preselections): New.
(Autoconf): Use it.
(m4_list_cmp): Use $0 to reinvoke yourself.
(m4_patsubsts): New.
(m4_strip, m4_version_unletter): Use it.
* tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH): Likewise.
* 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.
