Good question. In a really roundabout way it manages to be the same size as the alternative struct.

Edit: I missed that part of that was another union, removed what I said about it being off on 32 bit.

I still don't understand why they go so roundabout by dividing by one and casting to int...

Actually in C and C++, longs are 32 bit on most 32-bit platforms. If you need a 64-bit integer type, you need either "long long" or some implementation-specific equivalent.

I know that, I misread it as using two longs plus two pointers, fixed it now.
