Oops. Ok, my bad. It's apparently just a long-time gcc feature.
It's one that I was initially surprised by, but it's certainly a sensible
one from a type standpoint, and a lot better thought out than some gcc
extensions ;)
So I do actually like it. It's much nicer exactly for code like
if (somecase)
return that_case_handler();
where the type of the function to handle the case matches the type of the
calling function (regardless of whether that type is void or not, but
void obviously is a special case).
