config_* lists to config.status.
Don't recognize option --file, if the functionality is not there.
Likewise for --header; moreover, recognize --he and --h as shortcuts
for --help in that case.
directory have inherent problems with special characters like spaces,
due to limitations in Make syntax. Problem reported by Alexandre
Duret-Lutz.
* lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
Also, fix Tru64 porting problem with shell patterns,

from Justace Clutter.
* lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
variable into diagnostic. Make the diagnostic an error, not a warning,
because we really don't support spaces and suchlike in dir names.
(_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
Don't worry about backslashes in srcdir; it can't happen now.
(_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
Simplify ac_optarg handling.
(_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
* doc/autoconf.texi:
Don't mention Solaris versions so much, if a
problem is common to all extant versions of Solaris. Say "SunOS
4" instead of "SunOS" for SunOS 4.
(awk): Mention more of the limitations of traditional Awk.
(cat): Don't talk about cat -v.
(AS_VERSION_COMPARE): New macro. The API is taken from CVS,
but the implementation is entirely different and is designed
to be compatible with glibc strverscmp.
* tests/m4sh.at (AS_VERSION_COMPARE): New test.
"behavior" -> "behavior".
Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
* lib/autoconf/general.m4: Omit blank after ":" sed command,
as per POSIX.
* lib/m4sugar/m4sh.m4: Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
with Solaris sed. Fix by Stepan Kasal.

option. This runs afoul of a limit of 399 bytes per regular
expression on AIX. Problem reported by Ralf Wildenhues.

a line alone; the sed scripts to substitute them are now very
different.
(_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
commands can be put in a sed script portably.
* doc/autoconf.texi (Setting Output Variables): Document above
changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
use of multiline substitution.
* tests/torture.at: No longer expect substitution of newline to fail.
