Hi George

You are correct, you cant build x64 applications using GNAT GPL 20xx. 
However, you can however build/compile your own GNAT version using mingw64.

I find it easiest to cross compile/build GNAT on Linux, and then copy the
final distribution onto windows. Their are some detailed instructions on
how to do this on the mingw64 website. They also have some pre-build
distributions, BUT not all of them include GNAT/Ada
