The reason you get these warnings is because the objects being pointed
to are private types, as you figured out.  VADS must make the
assumption that they are of 32 bit integers after stating the warning.
Anyway, the binding does work even though there are warnings.  The
only ways I see to get rid of the warnings is to not have the private
types or to move the X_Windows_Interface package within the scope of
the private types.
