First a warning: if you run SunOS 4.1, but had your xterm built with
SunOS 4.0.x, you're at risk too.

Now my solution:

You can change the Imake.rules file to generate a non-relative path:
(TOP=$PWD, rather than .)

Instead of linking with -L../../lib/X -lX11, the linking will be done with
-L/usr/local/src/X11R4/lib/X -lX11 (on my system).

This is not a very good solution, because it hardwires TOP in the toplevel
Makefile. This will make it difficult to move the X source tree around.
(You must edit $(TOP)/Makefile, after moving)
