Coincidentally, just a few days ago, I tried to run Nim[0] on Windows XP as an experiment.

And to my surprise, the latest 32-bit release of Nim simply works out the box. But Nim compiles to C, so I also needed C compiler. Many versions of mingw I could find online - they all failed to launch.

After some time I managed to find very old Mingw (gcc 4.7.1) that have finally worked [1].

TCL/Tk 8.6 for XP, and as a bonus you get a gopher and gemini browser from gopher://hoi.st called BFG:

gopher://texto-plano.xyz:70/1/~anthk/bfgxp

Unzip the file and launch "lanzar.bat" in order to test it. I think I added tcllib and tklib just in case, so you can do a lot with that interpreter.

From what I remember doing it several years ago, it was not too hard to patch MSVC 2019 to run on (not just generate binaries for) XP.

I used CoLinux with pubuntu, and from there install GCC.

Anything for Win9x?
