	Jim, you sound like this is cruel & unusual.  I personally think
	if you use alloca, you get what you deserve (unportable code).

	But we should discourage it.  And the compiler usually needs to
	help anyway...  I don't consider #pragma alloca cruel or unusual
	at all.  Let's make people think about it before they use it
	(heck, C went ~15 years without it anyway).
