hmmm, interesting....
I don't know what a ONE_NOK is or what that syntax means
but I think your line* variables are arrays of pointers.
I just tried XORing two pointers and got your complaint,
so apparently GCC thinks they are not the same as integers.
Try explicitly casting them to ints, that seems to work.
