Any version that is not seriously outdated would do.  I guess 4.1 is
too old.  We don't specifically try out every single old version of
gcc so I can't be more precise than that.  If for some reason you
absolutely have to use gcc 4.1, you can probably translate with the
more portable "--gcrootfinder=shadowstack" option at the cost of a
some percents of final performance.

That's an unrelated question.  You can use either PyPy or CPython to
translate PyPy; it should only change the speed at which it is done.


A bientôt,
