Perhaps. It is also no real question that "bool" is the right return
type for a single bit. Changing that in all architectures at one time
is a major undertaking, however, and it seems to me that it would be
better to leave that to the respective architecture maintainers.
Perhaps I'm wrong, but I'd really like to avoid the upcasting to "int"
which isn't needed, because in my testing I find that it definitely
encourages gcc to generate poor code.
