Well I do not remember if I said this before.  Most of the  binaries
work fine except some of the  X11R4 binaries and most of MH binaries.
tcsh core dumped when it was called withing emacs and emacs (epoch?)
acted abnormal.

I have been told that there may be a version incompatibility, but 
I am runing the latest greates Ultrix 3.1c on all of my DEC (risk)
machines.

DEC is comming tomorrow and I am going to show them the problem.
