Input: sentelic - silence some underflow warnings
I have a static checker that complains when we check for an upper bound but don't have a corresponding check for a lower bound. With this code, the upper bound check seems not really required, so it is not a bug to leave the lower bound check out as well. But let's silence the warning by making these variables unsigned.
