You do need to be sure to compile code for the LCD of your machines: code 
compiled for a 68020 w/68881 may not run on a plain 68000 if it was compiled
with -k2l.  The default cc options generate code for a vanila 68000 - this 
code will run on a 68020 (optionally with a 68881/68882), but won't take 
advantage of the extra goodies on the 68020 (and 68881/68882).
