Update.

1998-07-31 17:59  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/bits/byteswap.h: Fix problems with side effects.

	* sunrpc/clnt_unix.c: Use ucred instead of cmsgcred again.
	(__msgwrite): Rewrite accordingly.
	* sunrpc/svc_unix.c: Likewise.
	* sysdeps/unix/sysv/linux/Dist: Remove __recvmsg.S and __sendmsg.S.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir)==socket]
	(sysdep_routines): Remove __sendmsg and __recvmsg.
	* sysdeps/unix/sysv/linux/__recvmsg.S: Removed.
	* sysdeps/unix/sysv/linux/__sendmsg.S: Removed.
	* sysdeps/unix/sysv/linux/recvmsg.c: Removed.
	* sysdeps/unix/sysv/linux/sendmsg.c: Removed.
	* sysdeps/unix/sysv/linux/recvmsg.S: New file.
	* sysdeps/unix/sysv/linux/sendmsg.S: New file.
	* sysdeps/unix/sysv/linux/bits/socket.h: Define SCM_CREDENTIALS and

1998-04-05  Jim Meyering  <meyering@ascend.com>

	* lib/regex.c (WIDE_CHAR_SUPPORT): Define.
	This now depends on HAVE_BTOWC so systems that lack btowc (like
	solaris-2.5.1) don't lose.

1998-08-07  Mark Kettenis  <kettenis@phys.uva.nl>

	* sysdeps/generic/bits/sigaction.h: Remove definition of SA_DISABLE.
	* sysdeps/generic/bits/sigstack.h: Define SS_DISABLE, SS_ONSTACK,

	* hurd/sigunwind.c (_hurdsig_longjmp_from_handler): Use SS_ONSTACK
	instead of SA_ONSTACK.
	* sysdeps/mach/hurd/sigaltstack.c (__sigaltstack): Renamed from
	sigaltstack, and created a weak alias.  Use SS_DISABLE and
	SS_ONSTACK instead of SA_DISABLE and SA_ONSTACK.
	* sysdeps/mach/hurd/sigstack.c (sigstack): Use SS_ONSTACK instead
	of SA_ONSTACK.  Call __sigaltstack instead of sigaltstack.
	* sysdeps/mach/hurd/i386/sigreturn.c (__sigreturn): Use SS_ONSTACK
	instead of SA_ONSTACK.
	* sysdeps/mach/hurd/alpha/sigreturn.c (__sigreturn): Likewise.

	Likewise.
	* sysdeps/mach/hurd/hppa/trampoline.c (_hurd_setup_sighandler):
	Likewise.
	* sysdeps/mach/hurd/mips/trampoline.c (_hurd_setup_sighandler):
	Likewise.
	* manual/signal.texi (Signal Stack): Talk about SS_DISABLE and
	SS_ONSTACK instead of SA_DISABLE and SA_ONSTACK in discussion of
	the `ss_flags' member of `struct sigaltstack'.

1998-08-05  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	[USE_IN_LIBIO]: Use _IO_fdopen instead of _IO_new_fdopen.
	* stdio-common/Version [GLIBC_2.1]: Add tmpfile.
	* stdio-common/tempnam.c: Use __strdup instead of strdup.
	* sysdeps/posix/fdopen.c: Define __fdopen and make fdopen weak
	alias.
	* sysdeps/generic/fdopen.c: Likewise.
	* sysdeps/mach/hurd/fdopen.c: Likewise.
	* stdio/stdio.h: Declare __fdopen.

	[USE_IN_LIBIO]: Map __fdopen to _IO_fdopen.
	* sysdeps/posix/tempname.c (__gen_tempname): Don't bother checking
	__stub_open64, it is never defined.

1998-08-05  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* libio/iofopen64.c: Fix typo.  Avoid unnessary casts.

	__grpalloc, __grpscan and the corresponding pwd functions, they
	were removed long ago.
