Thanks.

This looks pretty reasonable overall.  In order for it to go in, we
would need a couple things:

* Copyright assignment forms filed with the FSF.  If you don't have this
  already, one of us can get you started.

* A test case -- the one you have is fine, it just needs to be in the
  form used by our test suite.

It isn't 100% clear to me that cp_lookup_symbol_namespace is the right
function.  That file is kind of spaghetti-ish right now :(

I think lookup_typename is better here.

I think you should call check_typedef on scope_type before this check.
