  You're right, of course, but the standard doesn't forbid performing an
allignment on a pointer assign, does it? I don't have a copy here, but I
think we discussed this when someone said the standard *required*
alligning the pointer.

  Just because no sane person would do something doesn't mean it's forbidden.
