37d6a34e58 MSVC is a nimrod. (All verions 10.0 through 14.1) 
"(4074): error C4146: unary minus operator applied to unsigned type, result still unsigned"
So what?  Many programmers are much better than the typical Microsoft coder.
The C standard GUARANTEES that unsigned arithmetic uses two's complement,
ignores overflow, and the result is what the hardware adder produces.
