This is why assumptions like "bool will be one byte" that the standard doesn't guarantee shouldn't be made--to avoid exactly this sort of problem.

Aside from that, you now *know* it's problem, and you know that bool can change size moving between platforms. Hacking the compiler isn't optimal, except in a very short-term sense, because it *doesn't fix the bug*. It leaves it there, lying in wait for the next platform it bites you on. Why would you *not* want to *fix* the problem, instead of applying a band-aid? Why take the route that you *know* "could cause confusion in the future"?

Recall, too, that gcc is open source, and (I believe) Apple's version is available as part of the Darwin distribution. You don't have to wait for Apple to change it, nor depend on them *to* change it. You can add the switch yourself.
