Ryan Moeller 73d7820bba Use signed types to prevent subtraction overflow ... The difference between the sizes could be positive or negative. Leaving the types as unsigned means the result overflows when the difference is negative and removing the labs() means we'll have introduced a bug. The subtraction results in the correct value when the unsigned integer is interpreted as a signed integer by labs(). Clang doesn't see that we're doing a subtraction and abusing the types. It sees the result of the subtraction, an unsigned value, being passed to an absolute value function and emits a warning which we treat as an error.
