Fix -Wundef warnings in regex_internal.h
Commit Message
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.

* 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.
