Actually, it's fairly close to what I proposed. It even axed the addl after
the call. The only weirdness is the subl/addl dinking with gcc. I've no idea
what that is about. Perhaps it is using that to align code to a certain
boundary to optimize the ret inside printf? (Make it fetch at the start of a
cache line or some such.)
