I think it'd be worth identifying exactly which platforms have
sizeof(bool) different from 1. Are any of them things that anyone
cares about going forward? The point of this patch is to ease
future development of extensions, but it's unlikely any extension
authors care about portability onto, say, macOS 10.4 (prairiedog).
