That is because R3 xterm has a bug in it that MIT checks for in R4.  The
XGrabPointer call has an invalid mask.  To get around this (ie you don't
wanna fix the bug in the clients), run the R4 server in "bug
compatability" mode:  "Xdomain bc".  This bug has nothing to do with the
libraries or anything else and is very easy to fix or work around.
