Don't know.

But if you make the change to implement option 3, IMO it would be a good idea to add
the Python version number to the .pyd basename as well.

pywin32 already has to do this, since pythoncomXY.pyd and pywintypesXY.pyd
have to live (if possible) in the windows directory.

There have been other conflicts reported before: I remember Windows\system32\wmi.dll
conflicting with Tim Golden's wmi.py module.  In addition, wmi.dll is very special,
since it doesn't have an import table, IIRC.
