	* 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.

[ **] If a DSO is using implicitly libpthread and the application itself
does not there is a name lookup problem. E.g., the function fork()
will be found in the libc.so instead of libpthread since the thread
library is behind the libc. To correct this problem it must *not*
be relied on the currently still enabled handling of weak symbols
in the dynamic linker. Instead explicit tests for the availability
of the libpthread version are needed. [PR libc/2325]
