I intended to argue against the "only a warning", because the meaning of a warning in C is something very serious. That is different from more modern languages, who may use this to inform you that you are no longer writing idiomatic code. Of course there are also exceptions, that you often need to enable explicitly. But the fact that something is a warning in C, doesn't mean it's nothing serious, quite the opposite. That's my point.
