Wed Nov 20 02:04:11 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/sigsuspend.c: Make sigsuspend a weak
	alias of __sigsuspend.

	* grp/grp.h: Correct comment about POSIX compliance.
	* pwd/pwd.h: Likewise.

	* login/utmp.h: Update copyright and pretty-print prototypes.
	* sysdeps/generic/paths.h: Add _PATH_LASTLOG, _PATH_UTMP and
	_PATH_WTMP from utmpbits.h.
	* sysdeps/unix/sysv/linux/paths.h: Likewise.
	* sysdeps/generic/utmpbits.h: Remove here.
	* sysdeps/gnu/utmpbits.h: Likewise.

	* misc/sys/uio.h: Place __BEGIN_DECLS correctly.
	Pretty-print prototypes.

	* sysdeps/unix/sysv/linux/sparc/clone.S: New file.  Taken from
	LinuxThreads-0.5.

Tue Nov 19 13:43:07 1996  Richard Henderson  <rth@tamu.edu>

	* inet/ether_hton.c: Include <string.h>.
	* inet/ether_ntoh.c: Likewise.
	* inet/rexec.c: Get errno, index, getpass, getlogin from headers.
	* misc/search.h: Fix hcreate_r argument type (unsigned -> size_t).

	* misc/sys/cdefs.h: Change __long_double_t definition from typedef
	to define.  Jim Nance reports problems building XEmacs otherwise.

	* resolv/getnetnamadr.c: Likewise.
	* resolv/herror.c: Likewise.

	* sysdeps/generic/sigset.h (__SIGSETFN): Operator ## doesn't work
	with -traditional.  Reported by Eric Youngdale.  While we're at this,
	don't do error checking in the __ functions.  This is consistent
	with the sysv4 definitions and seems Right.
	* signal/signal.h: Don't __OPTIMIZE__ sigops to __ versions.  Add
	prototype for __sigsuspend.
	* sysdeps/posix/sigblock.c: Optimize sigmask <-> sigset_t conversions
	for sigset_t == unsigned long.  De-ansidecl-ify.  Reformat copyright.

	* sysdeps/posix/sigsetmask.c: Likewise.
	* sysdeps/posix/sigvec.c: Likewise.
	* sysdeps/posix/sigintr.c: Reformat copyright.
	* sysdeps/posix/signal.c: Check signal number out of range since
	__sigismember doesn't anymore.  Reformat copyright.
	* sysdeps/posix/sigwait.c: Use __ versions of sigfillset, sigismember,
	sigdelset, sigaction, and sigsuspend.

	* stdlib/drand48-iter.c (__drand48_iterate): Cast state fragments
	to the wider type before shifting.

	* sysdeps/alpha/bsd-_setjmp.S: Silence assembler warning "$at used
	without .set noat" in profiling hook.
	* sysdeps/alpha/bsd-setjmp.S: Likewise.
	* sysdeps/alpha/htonl.S: Likewise.
	* sysdeps/alpha/htons.S: Likewise.

	* sysdeps/unix/sysv/linux/alpha/llseek.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/sigsuspend.S: Likewise.  Rename
	function to __sigsuspend and add weak alias.
	* sysdeps/unix/sysv/linux/alpha/syscall.S: Likewise.  Add missing END.

	* sysdeps/alpha/w_sqrt.S: Define _ERRNO_H so <errnos.h> defines EDOM.

	* sysdeps/unix/execve.S: Match PSEUDO_END symbol with the symbol
	SYSCALL__ actually generated.

	* sysdeps/unix/sysv/linux/errnos.h [_LIBC_REENTRANT]: Reflexively
	#define __set_errno, as several imported subsystems (eg. BIND) check
	that the symbol is defined.

	* sysdeps/unix/sysv/linux/getsysstats.c: Include <alloca.h>.

	* sysdeps/alpha/memcpy.S: Temporarily remove until I can find a bug
	that manifests in GCC.

Tue Nov 19 11:10:05 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* sysdeps/posix/writev.c (writev): COUNT parm is now int.
	* sysdeps/posix/readv.c (readv): Likewise.

Tue Nov 19 15:28:29 1996  Ulrich Drepper  <drepper@cygnus.com>

	variable from __stat to __status to prevent shadowing.
	* sunrpc/rpc/clnt.h (clntudp_create, clntudp_bufcreate): Likewise
