Added return value to append_to_statement_list, so now it's:
*block = append_to_statement_list (*block, NULL);
That's different from what I was suggesting; if the list argument is a
pointer to a non-list, we can build up a list for at at that time, so we
don't need the
+ *block = append_to_statement_list (*block, NULL);
line at all; when we see
+ append_to_statement_list (build1 (LABEL_EXPR, void_type_node, label),
+ block);
if *block isn't a STATEMENT_LIST we just make the necessary adjustments.
