Nitpick: Windows is actually LLP64 (int and long are 32, long long and pointers are 64) and so it will work fine there. This is not to detract from your overall point in any way. If your code needs precise sizes, use a data type which specifies the size explicitly, like the standard int32_t and friends in stdint.h.
