That's interesting. I have installed X11.2 on my uVAX II under Ultrix 2.0
with -O turned on for all the compilations and I have not experience the
xterm or xbiff problems. So, if our optimizers are the same, your problem is
elsewhere. I hope to go to 2.2 soon -- and I will be recompiling everything,
even though the 2.0-generated binaries run fine on our 2.2 systems.
