Update.

	* sysdeps/ia64/bits/byteswap.h: New file.
	Patch by Dan Pop <Dan.Pop@cern.ch>.

	* misc/sys/cdefs.h: Define __attribute_format_arg__.
	* intl/libintl.h: Use it here instead of using __attribute__ directly.

2000-07-13  H.J. Lu  <hjl@gnu.org>

	* posix/regex.c (re_max_failures): Set to 4000.
