	* nis/nis_callback.c (internal_nis_do_callback) use poll()
	instead of select().

1999-08-02  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/s_nextafter.c: Define __nexttoward and
	nexttoward so something else so that aliasing works.

1999-08-02  Thorsten Kukuk  <kukuk@suse.de>

	* sysdeps/generic/math_ldbl.h: Fix typo.
	* sysdeps/generic/strtold.c: Remove unbalanced #endif.
	* sysdeps/alpha/fpu/e_sqrt.c: Use new path for e_sqrt.c.

1999-08-02  Ulrich Drepper  <drepper@cygnus.com>

	* elf/resolvfail.c: Include stdio.h.  Also test dlerror.

If you increase the number of file descriptors in the kernel you don't need

If your RPC daemons don't need more than FD_SETSIZE file descriptors, you
don't need to change anything at all.
