I'd prefer if the types were to remain 32-bit portable.

Doing things like this is just a problem waiting to happen,
either for the first person who actually finds a need and
a way to use this driver on 32-bit or the person who cut and
pastes this code into their driver which should work on both
32-bit and 64-bit.

Patch not applied.
