Recently I have wrote a program in Lightspeed C (3.0) with the compiler 
code generation options for the 68020/6881 on.  This program was then 
ran on the Mac II, Mac IIx, and the IIcx.  It only worked on the 
II.  And when the above options were turned off, compiled, and the 
application was built, it was not as fast as the MacII version.  

Does anybody know about these incompatibilities?  Why they exist -it 
seems illogical to me that the 68030/68882 would not support the 68020/
68881 codes - and what can I do to remedy this situation?  Do I have to 
label my applications according to the machine it is going to be run?

PS:  Thank you to those who have responded to my earlier questions about 
masking the menu bar.  I am still working on couple of the suggestions, since 
the first two I have receieved did not work out the way I wanted.  But I'll 
let you know as soon as I get it working.  Thanks, again.
