The first thing you need to do if you're using cvs is check out the
cvs version of the sources.  This creates a "working directory" that
includes information that cvs uses to keep track of what your changes
are.

If you want to compare a non-cvs source tree with cvs, you'll have to
check out a cvs tree elsewhere on your local drive and do a local
diff.
