But since they don't come from the same CVS tree, I can't see how to do
that cleanly without dicking around with the common code directories such
as libiberty and include -- experience has shown that with the public CVS
repositories that is fraught with problems. I have done it in the past,
but it breaks the principal that the sources you are testing are the
sources you are committing, so it isn't really a viable option.
