Update.

* 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.

* posix/wordexp-test.c: Undo last change.
