I'm not very fond of the code duplication either.
The only way I can think of, is to refactor it into template functions that
can accept both CONTEXT or WOW64_CONTEXT.
Is this what you had in mind also, or do you have a better idea?

Yes, I can do that.
I didn't even know that configure.nat was the place for this, that's why I
did it with the include.
