I will give it a try. All methods would have to be moved into the header
of course.

What if we used int64_t consistently instead of ptrdiff_t?
Sci::Position would be 64-bit even on 32-bit platforms.
I guess this wouldn't be tolerable?
Perhaps we could also detect 64-bit and conditionally typedef to
int32_t or int64_t. We then would at least know what it aliases to,
therefore fixing the #if (INT64_MAX != INT_MAX) approach.
