I just had the same thing happen to me.  I was somewhat surprised that lint
complained, because I've always considered that to be a valid operation even
in the strict-enum model.  My workaround was to write a macro
  #define enum_foo_lt(x,y) ((int)(x) < (int)y)
, but I dislike this because it doesn't typecheck the arguments (it will now
let me compare an enum foo with an int, which *should* be illegal in this
model).
