In reply to the general discussion on heap block and stack alignment:

Since we know that both heap blocks and elements on the stack are at least
word-aligned on every Macintosh, then perhaps it's best to just assume that
alignment for all Macs (whether 68000 or '020,'030) so that one's software
is compatible with all Macs.  Unless one knows one is runing on an '020 or
'030.

Of course, one shouldn't assume too much about low-level aspects of the Mac
since they have a notorious habit of changing...
