It seems to me that the real problem here is that it isn't meaningful to perform (a-b) on unsigned integers when (a<b). Attempting to clean up the resultant mess is really papering over the problem. How about a runtime error instead, much like dividing by 0?
1. Yes it is meaningful - depending on what you're doing. 2. Such a runtime test is expensive in terms of performance and code bloat.
