I agree that this patch was broken; the _Environ stuff was in the else
part before. The change was committed by gvanrossum; the checkin
comment says that its author was dschwertberger.

I agree. What it seems to say is 'even though riscos does have a
putenv, we cannot/should not/must not wrap environ with a UserDict.'

I'd suggest to back-out this part of the patch, unless a consistent
story can be given RSN.

P.S. os.py mentions an "import riscos". Where is that module?
