If I had to guess, I'd say yes - but guessing is dangerous.  It's easy to
check the lower 2 bits to find out, though.

Other platforms would (presumably) have different penalties for different
alignments, so imposing the Intel alignment on them makes no sense.

As in, Borland or MS?  I wouldn't assume anything about them.
