sizeof(DWORD) is always 4, even on 64-bit windows. sizeof(long) is also
always 4. If you want the unsigned integral type that is the same size as
pointers, there are some MS-defined types you can use: DWORD_PTR,
LONG_PTR, ULONG_PTR. Or use the standard size_t and ptrdiff_t.

Which is why 64-bit windows is not supported. Hopefully at some point
someone can remove this restriction, but it is likely to be a major

August. The lines are the shortest, though.
