	* sysdeps/libm-i387/s_expm1.S: Change return value for -inf
	* sysdeps/libm-i387/s_expm1f.S: Likewise.
	* sysdeps/libm-i387/s_expm1l.S: Likewise.
	* sysdeps/libm-i387/s_isinfl.c: Return -1 for -inf.
	* sysdeps/libm-i387/s_logbl.S: Correct return value.  Discard first
	* sysdeps/libm-ieee754/w_powf.c: Likewise.
	* sysdeps/libm-ieee754/w_powl.c: Likewise.
	* sysdeps/unix/sysv/linux/alpha/statbuf.h: Likewise.
	* nss/nss_files/files-hosts.c: Likewise.
	Based on a patch by H.J. Lu <hjl@gnu.ai.mit.edu>.
	* nis/ypclnt.c (__yp_bind): Fix possible buffer overflow.
