I don't mean different versions, I mean toolchains that cover all 
architectures.  If I don't have a superh or blackfin compiler installed, 
I'm not going to see any warnings on those boards because they won't 
build at all.

I agree though that it would be nice to grep for existing NAND users and 
try to cover the obvious ones.
