Hmm.. I'm sure I checked __mc68000__...must have missed something. I've
finally had a look at Eric's patches for m68k.h and I'll modify my code to
match..I think my home mail program ate the attachment or something...
Looking at the number of instances of #ifdef m5200 in my code it's perhaps
time I did a bit of a rewrite and used a new #define M68K_IS_COLDFIRE_ARCH
rather than some explicit processor reference which was/is dumb.

I hope it doesn't get supported in gcc...getting solid ColdFire support has
proved a significant problem. The MAC instructions will need to be added to
binutils though but I think I'll let somebody with a chip deal with that
Thanks for the pointers,
