    * c-decl.c (c_push_function_context): Restore the behavior to reuse
    the language function allocated for -Wunused-local-typedefs.
    (c_pop_function_context): If necessary, clear the language function
    created in c_push_function_context.  Always clear out the
    x_cur_stmt_list field of the restored language function.
