I'm a bit surprised that Red still seems stuck at 32 bits, like it was last time I saw something about it years ago. What is the roadblock that prevents them from building 64-bit binaries? I guess it must be very hard since otherwise it would have already been fixed.

i think the holdup is the lack of self-hosting. probably the rebol compiler they use can only build 32bit binaries so self-hosting and 64bit support go together.

it's on the milestone for 1.0. and according to the roadmap 1.0 is a solid year of work. it's likely not the only thing they want to do for 1.0, but i guess self-hosting is a big chunk

No, even Rebol2 can build 64 bit but the whole compiler needs to be rewritten to produce 64 bit binaries. It’s not limitation but deliberate choice made when 32 bit was still major target. It may seem silly in the hindsight. But it made sense then.
