AC_FUNC_FNMATCH now tests only for POSIX compatibility.

AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
Both macros now accept an optional source-dir arg.
New macro AC_GNU_SOURCE to define _GNU_SOURCE.

* NEWS: Document this.
* doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.

* lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
(AC_FUNC_FNMATCH): Use it.  Test only for POSIX conformance,
not for GNU extensions; this undoes part of the 2000-11-03 change,
reverting to 2.13-compatible behavior.
Add new optional argument DIR.
(AC_FUNC_FNMATCH_GNU): New macro.

* lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
