Update.

2003-11-17  Jakub Jelinek  <jakub@redhat.com>

	* posix/regcomp.c (optimize_utf8): Optimize multi-byte chars as
	well.
	* posix/bug-regex20.c (tests): Add new tests.  Multi-byte char
	followed by dup operator is expected to be optimized.

	* posix/regexec.c (check_node_accept_bytes): Move nrules and j
	variables to the block where they are only used, initialize
	nrules only immediately before using it.

2003-11-15  Andreas Jaeger  <aj@suse.de>

	* sysdeps/x86_64/fpu/s_scalbnl.S: New file.
	* sysdeps/x86_64/fpu/s_truncl.S: New file.
	* sysdeps/x86_64/fpu/s_nearbyintl.S: New file.
	* sysdeps/x86_64/fpu/s_floorl.S: New file.
	* sysdeps/x86_64/fpu/s_ilogbl.S: New file.
	* sysdeps/x86_64/fpu/e_remainderl.S: New file.

	* math/libm-test.inc (floor_test): Test also ±0.25.
	(ceil_test): Test -0.25.
