Yes, I'm just not sure the right approach. It would be wasteful to
return the comparison function from the annotation function every time
it's called, since it's the same for every call.

Would it be OK for compile.el to start storing this data in a variable?
The number of errors/warnings/infos is already stored; also storing the
exit status would probably be useful for all kinds of things.
