No, not really.  But I think a good way of cleaning it up is to try to
merge it with the telnet code in crypto/dist/heimdal since we have
done lots of cleanups there. :-)

UNICOS5 is old and ancient.  CRAY2 the same.  CRAY (or _CRAY) might
actually be needed for weird pty handling on crays.  The telnetd code
in heimdal has these still there and actually builds on crays.
Same with _SC_CRAY_SECURE_SYS.
