I also once tried compiling kernel with -m68040. I got the same
results and got back to -m68020-40 which again worked.
As far as I recall there was only one file with which the compile
produced an error and that was one of the Amiga specific files. Can't
remember now which one but I can check it quickly.
The kernel did compile/work cleanly even when I used -m68040 for every
file but that one particular file.
