acinclude.m4 (enable_cshadow_headers): Change CSHADOWFLAGS to _GNU_SOURCE instead of _ISOC9X_SOURCE...

2000-06-13  Benjamin Kosnik  <bkoz@redhat.com>

       	* acinclude.m4 (enable_cshadow_headers): Change CSHADOWFLAGS to
	_GNU_SOURCE instead of _ISOC9X_SOURCE, as _GNU_SOURCE is the
	superset, and already defined at top level.
        * aclocal.m4: Regenerate.
        * configure: Regenerate.
