Removed warnings on ignored aligns. Only do aligment on packed structs, align(1) struct Packed { ... } Changed the way struct/class fields are added, first small part of cleaning up these... Make struct/class/union fields aware of any anonymous struct/union they might be part of, not yet really useful, but part of getting better union support.
