zeromus, 

(l706) I am okay with these optimizations, even if they don't help much.
But you really, really should avoid giving your macros/variables such...
terrible names. This really looks terrible and unclear.

After waiting a while for you or somebody else to rename those vars/macros, 
I finally decided to do it myself because they were bugging me. It's okay 
for this time, but the next time I see such terrible names in a commit, I'll
just revert it.
