Update.
2001-06-14  Roland McGrath  <roland@frob.com>

	* configure.in: Let sysdeps Implies files in add-ons bring in
	sysdeps directories from the main source and other add-ons too.

2001-06-15  Jakub Jelinek  <jakub@redhat.com>

	* math/test-misc.c (main): Add tests for nextafter and nexttoward
	with +-Inf as second argument.

	* sysdeps/generic/s_nexttowardf.c (__nexttowardf): Only check for
	NaN, not Inf.
	* sysdeps/i386/fpu/s_nextafterl.c (__nextafterl): Fix check for NaN.
	* sysdeps/i386/fpu/s_nexttoward.c: New.
	* sysdeps/i386/fpu/s_nexttowardf.c: New.
	* sysdeps/ieee754/ldbl-96/s_nexttoward.c (__nexttoward): Simplify
	check for NaN, optimize x==+-0 handling.
	* sysdeps/ieee754/ldbl-96/s_nexttowardf.c (__nexttowardf): Likewise.
	* sysdeps/ieee754/ldbl-96/s_nextafterl.c (__nextafterl): Simplify
	check for NaN, fix sign in x==+-0 case.
	* sysdeps/ia64/fpu/s_nexttoward.c: New.
	* sysdeps/ia64/fpu/s_nexttowardf.c: New.

2001-06-15  H.J. Lu  <hjl@gnu.org>

	* rt/tst-aio2.c (do_test): Initialize cb.aio_offset to 0.
	* rt/tst-aio3.c (do_test): Likewise.
	* rt/tst-aio4.c (do_test): Likewise.
	* rt/tst-aio5.c (do_test): Likewise.
	* rt/tst-aio6.c (do_test): Likewise.
