I knew there was a reason I disliked PPC

You should maybe put a do { ... } while(false) around those conditionals, or you can get unexpected results if someone should use them in an if...else statement

@bionicbeagle: sure, and we do have a do..while around most of these macros, but not around this one. Maybe someday someone will fix it :)
