Update.

	* nis/ypclnt.c (__yp_bind): Pretty print.  Optimize readv result
	check a bit.  Also close socket of domain client.  Close socket
	in IPPORT_RESERVED error case.

1998-09-28  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/bits/socket.h (__cmsg_nxthdr): Use
	CMSG_ALIGN (fixes a bug) and correct test for availability of
	another entry.
	* sysdeps/unix/sysv/linux/mips/bits/socket.h: Sync with generic
	Linux version.
	(__cmsg_nxthdr): Use CMSG_ALIGN (fixes a bug) and correct test for
	availability of another entry.
	Patch by ak@muc.de.

	* sysdeps/unix/sysv/linux/netinet/ip.h (IPOPT_NOOP): Fix typo.
	Patch by ak@muc.de.

1998-09-27  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* posix/annexc.c (xsystem): New function.  Use it instead of
	system.

1998-09-28  Ulrich Drepper  <drepper@cygnus.com>

	* stdlib/longlong.h: Remove #endif for #if removed in last change.
