	Make the handling of the configuration links (AC_LINK_FILES)
	exactly the same as that of configurations files (AC_OUTPUT_FILES)
	and headers (AC_CONFIG_HEADERS).  As a result, it is sane to run
	        ./config.status src/libmy_lib
	or
	        CONFIG_LINKS=src/lib_mylib:lib/lib_mylib ./config.status

        * acgeneral.m4 (AC_LINK_FILES): Use AC_FATAL to diagnose bad
	number of argument.
	Obsoleted (but implemented) in favor of AC_CONFIG_LINKS.

	* acgeneral.m4 (AC_CONFIG_LINKS): New macro.  Takes space
	separated list of DEST:SOURCES arguments.
	* acgeneral.m4 (AC_OUTPUT_LINKS): Adapted to the new scheme of
	AC_LIST_LINKS.
	* autoconf.texi (Output, AC_OUTPUT): Mention AC_CONFIG_LINKS.
	(Invoking config.status): Mention CONFIG_LINKS.

	obsoleteness of AC_LINK_FILES.
