<- That's a very good suggestion, hand assemblying the 68020 code.  If
you're worried about this, borrow someone's 68020 assembler (MPW or
otherwise, maybe not even macintosh-based), and write the MUL.L
instructions you want.  The assemble the code and get a listing.
Write down the hex and take it back to LightspeedC, and stuff it in
an asm { } using constant-word expressions.

This technique is nice because you hardly have to think at all....
