Update.

1999-12-17  Ulrich Drepper  <drepper@cygnus.com>

	* string/bits/string2.h (__strtok_r_1c): Help gcc optimizing string
	access.

	* locale/programs/ld-collate.c: Implement handling of absolute
	ellipsis.  Parsing of file and constructing the internal data
	structures should now be complete.
	(collate_finish): Start adding support to generate the data
	structures which are written out to the file.

	* intl/dcgettext.c: Rewrite to handle caching of previous results here
	instead of in the dcgettext macro.
	* intl/libintl.h (dcgettext): Don't define for systems using this
	glibc or systems with tsearch.

	* sysdeps/generic/mathdef.h: Protect definitions for math.h
	against double inclusion.
	* sysdeps/alpha/fpu/bits/mathdef.h: Likewise.
	* sysdeps/i386/fpu/bits/mathdef.h: Likewise.
	* sysdeps/m68k/fpu/bits/mathdef.h: Likewise.
	* sysdeps/powerpc/fpu/bits/mathdef.h: Likewise.

	* sysdeps/i386/fpu/libm-test-ulps: Add more deltas (are mobile PIIs
	that different?).

1999-12-17  Andreas Jaeger  <aj@suse.de>

	* rt/aio.h (struct aiocb64): Add member __next_prio to sync the
	struct with aiocb.

	* rt/Makefile (tests): Added tst-aio64.
	Added dependency rules for tst-aio64.

	* rt/tst-aio64.c: New file, copied from tst-aio.c and changed for
	64bit tests.

1999-12-15  Thorsten Kukuk  <kukuk@suse.de>

	pointer of last cursor element.
	(insert_value): Return nonzero value if nothing got inserted.

1999-12-14  Andreas Jaeger  <aj@suse.de>

	* string/tester.c (test_strsep): More tests for access beyond
	the final NUL.  The first two tests come from PR libc/1486 by
	martinea@iro.umontreal.ca.
