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.

	* resolv/herror.c: Likewise.

	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/sigvec.c: Likewise.

	* 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.

	without .set noat" in profiling hook.
	* sysdeps/alpha/bsd-setjmp.S: Likewise.
	* sysdeps/alpha/htonl.S: Likewise.

	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>
