The problem you are having is caused by the fact that the ps program tries
to read the system namelist from /xenix.  If you are not running /xenix,
the ps command will fail.  This problem should be solved when you copy
the kernel from /usr/sys/conf to the root directory /xenix.

Use the -LARGE option is the cc invocation line.  This use large model
passes of the compiler which have room for more symbols.
