I haven't tried to put up X11 yet on the multimax.  You will probably
hit the same problems I had with X10.  Bcopy() doesn't handle overlapping
strings properly.  This shows up while backwards scrolling and inserting
in vi.  Bzero cannot zero 1-3 bytes correctly.  4 bytes are zeroed in
these cases.

I can post fixes to the bcopy and bzero problems if people want.

I have had problems with select as well.  Select when given a NULL pointer
to the timeout would return instantly with no descriptors ready and a
return value of zero.  Xterm core dumped almost immediately.  This problem
may have been fixed in later versions.

Xload needs a bit of work since the load average is computed differently.
Nlist() is not a valid operation and avenrun does not contain the load.

As for the problems with include nesting, there is a compiler switch which
may be used to run cpp external to the normal C compiler first.  (I seem
to remember this being correct.)  This might be an easier way to do things.
