   They follow from a couple of facts:   
   Each element in an array of type T must be correctly aligned for an   
   object of type T.   
   No space is allowed between the elements of an array. Note, in   
   particular, that this implies that if a type uses only 3 bytes, but has   
   an alignment requirement of 2, it must be padded to a length of 4 bytes,   
   and sizeof(T) must reflect that size, and not the number of bytes that   
   the type actually uses.
