The only way to reproduce this is to be running the interpreter
with the -Qwarnall option; ``./python.exe -Qwarnall -c "import
random"`` will reproduce it. But if you run ``./python.exe -Qnew
-c "import random" `` everything is fine.
All of this has to do with true division that will become the default
in Python 3. -Qwarnall warns about *all* division, even when the
mathematical outcome of the division is the same regardless of
whether ``from __future__ import division`` (which can also be
done on the command-line by passing the -Qnew option) was run
or not.
In other words there is nothing to worry about here. I am closing
this as "won't fix".
