1998-09-17 19:34  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/sysv4/bits/utsname.h: Fix typo.
	Patch by John Tobey <jtobey@banta-im.com>.

1998-09-17  Mark Kettenis  <kettenis@phys.uva.nl>

	* login/pty-internal.h: Removed.  Moved constants related to the
	`grantpt' helper program protocol to ...
	* login/pty-private.h: ... here.  New file.
	* sysdeps/unix/sysv/linux/ptsname.c (ptsname): Reimplementation
	to make the function work with kernels >= 2.1.115.
	* sysdeps/unix/sysv/linux/getpt.c (getpt): Reimplement to call BSD
	version if using the cloning device fails.
	* sysdeps/unix/sysv/linux/grantpt.c: New file.
	* sysdeps/unix/sysv/linux/unlockpt.c: General cleanup.
	* sysdeps/unix/bsd/getpt.c (__getpt): Largely rewritten to allow
	use by Linux specific code.
	* sysdeps/unix/bsd/unlockpt.c: General cleanup.
	* sysdeps/unix/grantpt.c: Largely rewritten.  (pts_name): New
	function.  (grantpt): Use pts_name, check group and permission
	mode in addition to owner.  Try to set the owner, group and
	permission mode first without invoking the helper program.
	* login/programs/pt_chown.c: Largely rewritten.  Add argp and
	internationalization support.  Use symbolic constants instead of
	hardwired numbers for permission mode.
	* sysdeps/unix/bsd/ptsname.c: New file.
