One thing I have always wondered (Julian and Gryf might have
interresting answers to this one too):

Is there a way to support anything from the 68881 as a 68020/030
coprocessor, to the built-in FPU in a 68040/060, using the same
compiler options?

Btw, as far as I can tell, the ASM line in your specs _does_
transform mc680* into 68000.  Most other lines in your specs
seem to support either 68000 or 68020-60 and nothing else.

This 68020-60 flag is not a bad idea, in itself, as it simplifies
compiling binaries for a larger range of hardware, but it _does_
mean code that is somewhat less optimized than it could be.
