And my argument is: what the hell does this _buy_ us, except for extra 
complexity, and even more code dependence on different versions of gcc.

I don't want the extra code-paths and magic #ifdef's unless there's a 
clear improvement somewhere. And quite frankly, I don't see that being the 
case for something like ffs.
