Update.

1999-03-13  Mark Kettenis  <kettenis@gnu.org>

	* sysdeps/unix/bsd/getpt.c (__getpt): Do not use `isatty' to check
	if the opened master pty really is a pty.  `isatty' checks for
	tty-ness and a pty is not a tty.  Return ENOENT instead of ENFILE
	if we are out of pty's.

1999-03-13  Mark Kettenis  <kettenis@gnu.org>

	* sysdeps/generic/utmp_file.c (setutent_file): Make sure the just
	opened file is closed on exec.
	* login/utmp_daemon.c (setutent_daemon): Likewise for the just
	opened socket.

1999-03-13  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* manual/llio.texi (File Position Primitive): Reformat @end
	command.  Patch by Bruno Haible <haible@ilog.fr> [PR libc/1020].

	* nscd/nscd_getpw_r.c (nscd_getpw_r): Set `errno' correctly if no
	entry is found.
	* nscd/nscd_getgr_r.c (nscd_getgr_r): Likewise.
	* nscd/nscd_gethst_r.c (nscd_gethst_r): Likewise.
