VC++ 2017's STL doesn't suppress warnings as aggressively as prior versions did. This causes warnings on code which mixes signed and unsigned types. In this case a deque of unsigned integers was being queried to see how many signed integers it contains. This could be fixed by passing in unsigned 0, 1, and 2 to std::count but changing the deque from unsigned to int is simpler.
