Since the array's size depends on a generic parameter, there is no way
to obtain a static size for the array to use in a rep spec. The only way
is to specify the components that come before the array, pack the
record, and hope the compiler positions everything where you need it.

If Integer'Size is 32, this is the same as My_Array'Size.
