I was amused the first time I saw this trick. However, your vehicle
is a poor choice to implement it in. Why don't you just round up
the number of int's (long's, whatever) to the next multiple of eight,
allocate that much space, & then you wouldn't need the switch. Nobody
cares about a few extra bytes when they do [mc]alloc's.
