AC_LANG_FUNC_LINK_TRY. This involves returning the value returned

The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
and CONFIG_COMMANDS are not processed in four separate loops.
Instead, there is one main loop. This alows that the common code
is expanded only once, thus config.status (and configure) is smaller.
The registration mechnism in AC_CONFIG_FILES and cousins also changed;
the AC_LIST_FILES and cousins macros are no longer used.
* lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
(_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
_AC_OUTPUT_COMMAND): ..., respectively. These macros no longer

commands; all these go to ...
(_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
_AC_OUTPUT_CONFIG_STATUS.
(_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
(_AC_OUTPUT_FILE): The creation of the sed script ...
(AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
(_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from

(AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
AC_LIST_COMMAND_COMMANDS): Replaced by this ...
(_AC_LIST_TAG_COMMANDS): ... new common macro.
(_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
this didn't belong to the `config commands' section.
(_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
(AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
to the `config commands' section either.
(AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
(_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
... and many changes to the comments nearby.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
set ac_subdirs_all='_AC_LIST_SUBDIRS'.
* tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
(#define header templates): The comment at the top of the generated
header now includes the name(s) of the source file(s).
Several unrelated small changes:
* lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
parameter to AC_DIAGNOSE.
* lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
(_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
(AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
with AU::AC_OUTPUT.
(AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
in AC_OUTPUT doesn't double-quote it either.
* tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
parameters.

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.

4" instead of "SunOS" for SunOS 4.
(awk): Mention more of the limitations of traditional Awk.

man pages every month.
* doc/autoconf.texi (Introduction): Likewise.
Reword to avoid some formatting glitches.
Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
Clarify explanation of HP compiler bug.
Redo example output tp match current CVS snapshot.
Use @example.org in email addresses when the examples
might get inadvertently cut-and-pasted into user code.
Remove example of autom4te usage that doesn't seem to work now.
Use modern AC_INIT (except when the example is meant to be
shown with Autoconf 2.13).
Update ksh info for Solaris 9 and later.

* lib/autoconf/functions.m4
(AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
Don't bother to remove core files; AC_RUN_IFELSE should do that for you.

".)" needs a following @: if not at the end of a sentence, and
similarly for "!)". "etc." should be preceded by a comma.
"n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
(Input): Mention that AC_CONFIG_AUX_DIR's
argument is often called 'build-aux'.
