        * trans-decl.c (gfc_get_module_backend_decl): Also copy
        ts.u.derived from the gsym if the ts.type is BT_CLASS.
        (gfc_get_extern_function_decl): Copy also the backend_decl
        for the symbol's ts.u.{derived,cl} from the gsym.
        * trans-types.c (gfc_copy_dt_decls_ifequal): Directly
        return if "from" and "to" are the same.
