Could this perhaps be represented by _one_ struct definition and two representations of it, one for swapped and one for non-swapped case or so? (although sometimes it´s reverted logic, might need more thought) Sounds like an awful lot of repeated array calculations for no overly good reason (unless gcc happens to fully optimize it into oblivion automatically).
