There's nothing to fix there.

ISO:	int <= int - 1
K&R:	int <= unsigned int - 1

I.e we lose the unsigned losage after having assigned the value
to the signed integer variable, so the comparison isn't affected.
The problem can only arise when there's arithmetic as one of the
operands to a comparison.

I hate casts, so I don't want to proliferate them without need.
