[pypy-dev] pypy 3.6 and WinXP

[Joseph Jenne]

I don't have much experience with the windows side of pypy, especially 
on XP, but I would suggest trying to compile for your system, as I do 
not know of any reasons for incompatibility. That said, perhaps using a 
somewhat older version might be preferable, depending on the specifics 
of your use case
