        * class.c (gfc_find_derived_vtab): Mark __vtab and
        __def_init as FL_VARIABLE not as FL_PARAMETER.
        * expr.c (gfc_simplify_expr): Remove special
        handling of __vtab.
        * resolve.c (resolve_values): Ditto.
        * trans-decl.c (gfc_get_symbol_decl): Mark __vtab
        and __def_init as TREE_READONLY.
