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.
