Yes, but if you looked at what the code *does*, you would see that you
don't want to execute those statements.

In this case it wouldn't. Here's a goto-less version of the multiple
lead-in case that should have you all puking:

	switch(format_char) {
		case 'd': the stuff I put under d; if(0) {
		case 'o': the stuff I put under o; if(0) {
		case 'x': the stuff I put under x; if(0) {
		case 'u': the stuff I put under u; }}}
			the stuff I put under donum;
	}

I know it's not the best way to remove the gotos, but it's legal C
without a single "unstructured" element.

It's always possible to "remove" the gotos. It's not always worth it.
Structured programming is a discipline, not a game.
