A fix seems *so* easy: just remove the error!

      if (cp_type_quals (base) != 0)
    {
      error ("base class %qT has cv qualifiers", base);
      base = TYPE_MAIN_VARIANT (base);
    }
      result = build_tree_list (access, base);
      if (virtual_p)
    TREE_TYPE (result) = integer_type_node;
