  Hi,

This patch defines macros that gnulib looks for and also syncs up the
macro check with gnulib.  No change in generated code on i686.

Siddhesh

	* include/libc-symbols.h (HAVE_LIBINTL_H): Define macro.
	(HAVE_WCTYPE_H): Likewise.
	(HAVE_ISWCTYPE): Likewise.
	(ENABLE_NLS): Likewise.
	* posix/regex_internal.h [(defined MB_CUR_MAX && HAVE_WCTYPE_H
	&& HAVE_ISWCTYPE) || _LIBC]: Sync up with gnulib.

OK, but you should follow up with gnulib to clean up all unnecessary _LIBC
tests and then re-synch our copies.

Ack, I'll do a more comprehensive synch when 2.21 opens.
