Hi Jon. Frankly Are you 100% sure (in terms of middle-end/back-end details)
that the maximum alignment supported for a type of less than 4 bytes is 4? In
that case, your proposal of using  __aligned__((_Len)) certainly makes sense. I
wasn't sure at the time and picked a "safe" choice, probably should have
asked...
