I don't think you can do that with CVS.  I don't know CVS too
much, but the times I tried I ran into problems when branches
were involved (I was getting diffs against tip of branch or HEAD,
IIRC).

My SPEC testers work around this problem by doing:

$ cp -a gcc gcc.prev
$ cvs update
$ diff -r -x CVS gcc.prev gcc
