       * tree.c (build_type_attribute_qual_variant): Hash on the
       unqualified type, and don't overwrite an existing
       (type_hash_eq): Make the TYPE_NAME of the types significant, to
       allow distinguishing between wchar_t and its underlying type. This
       also means that we'll retain a little more typedef information.
