Structures are not aligned to the size of the largest element, but
to the largest alignment needed for each member.
This can be smaller than the size of the largest element.
E.g. alignof(long long) might be 4, not 8.  And m68k aligns to
two bytes at most.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
