I'd asked just that question a couple of months ago and didn't
receive much in the way of response.

One thing that'll be different is the way you do floating point.
Apparently on 68010's you have to do some fairly complicated things
to access the '881 and usually that stuff is in the run-time
library.  On the '020 it's easier and doesn't get put off into
subroutines.  The point being that your compiler'll have to be
a bit different.  (On the other hand -- doesn't gnu CC handle
the '881 already?).

Something else which occurs is that there might be some hardware
assumption because the Amiga doesn't have an MMU and has certain
other things while the Unix PC has an MMU and doesn't have certain
other things.  &etc.

It would be loverly to have an 020 in there tho'.
