OpenSSH-3.5p1: sshd fails at run-time

[Ben Lindstrom]

It is Either Compression or PrivSep.  You don't need to turn off both.

Hmm.. LynxOS mmap() looks incomplete.. You can always take and uncomment
HAVE_MMAP in your config.h  and recompile.  That should resolve to the
last method of handling compression/privsep communications.

It would be nice if we could get someone who knows something about LynxOS
(Hey, Anyone from LynxOS developers group here?!) to give us a suggestion
on the best fix.
