Jakub has already shown correct x64 code being generated by gcc 3.2.3. Maybe they used an emulator or something. And I already have it running myself - with small modifications for MSABI - on Windows 10 64-bit - for my pdptest test program. The only thing not working for me at the moment that I know about is negative indexes. And that is something specific to my derivative (or more likely the way I built it), not standard gcc 3.2.3.
