I think so.
Alignment is defined informally as:
3.2
[#1] alignment
requirement that objects of a particular type be located on
storage boundaries with addresses that are particular
multiples of a byte address
This definition is independent of the size of the type. Furthermore,
there's no way to determine the required alignment of a type.
