OpenSSH-3.5p1: sshd fails at run-time

[David M. Williams]

turn off Compression and PrivSeperation in your sshd_config file and try 
again.  From what the the threads in June mention it looks like your 
flavor of LynxOS has a broken mmap.

Can you send the build and system info from the config.log file created 
in your build directory?  It will help to improve the configure tests 
for mmap.
