How does that help?

There was talk of porting VFP to 64 bit by the Fox development team many years ago, and it was basically abandoned as impossible without a full re-write. FoxPro's code base dates back to CP/M days and there's a lot of code that specifically depends on bitsizes and processor specific implements. The 32 bit re-write was a major re-write to get VFP to run 32 bit code, but doing that again was deemed too difficult to attempt without a re-write.

I've seen some of the VFP source code and I can tell you it's not the most straight forward C++ code and it certainly won't cross-compile with anything but 32 bit Windows code. It's highly optimized code that's written specifically for the platform it was designed for - porting that - even if there was anybody who could do that today with no team - would be near impossible. A re-write would likely be way easier.
