1997-03-17 04:00  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/libmieee754/w_atan2.c: Don't ignore exception if library
	type is SVID.
	* sysdeps/libmieee754/w_atan2f.c: Likewise.
	* sysdeps/libmieee754/w_atan2l.c: Likewise.

	* sysdeps/unix/sysv/linux/sys/mman.h (msync): Add descrption for
	FLAGS parameter.

	* sysdeps/unix/sysv/linux/socketbits.h: Add more SOL_ values.
	Change msg_iovlen and msg_controllen (in struct msghdr) to
	`size_t' to keep in step with kernel.

	* manual/examples/dir2.c: New example for scandir.
	* math/test/float.c: New file.  Frontend for float tests.
	* math/test/double.c: New file.  Frontend for double tests.
	* math/test/longdouble.c: New file.  Frontend for long double  tests.
	* sysdeps/ieee754/huge_val.h: Remove definition of long double
	* sysdeps/libm-i387/s_scalbn.S: Likewise.
	* sysdeps/libm-i387/s_scalbnf.S: Likewise.
	* sysdeps/libm-i387/s_scalbnl.S: Likewise.
	* 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.
	* posix/unistd.h: Add prototype for __euidaccess.
