I do my own move layout for the sake of portability, freeness of endianess and the possility of making domain specific tunings. Speed isn't a reason for me. First of all, the speed difference haven't been that great at all, secondly it varies wildy with different compilers (which of course is a reason _not_ to use bitfields), but most importantly, whether it takes x or 10x doesn't affect my NPS at noticably at all. /David
