 OK, but GRASS is compiled "with" a particular Python version, for ctypes.
 And apparently wxversion is needed which is only available in a devel
 package (Linux).

 > If the .py extension hasn't been associated with a Python interpreter,
 executing Python scripts won't work, with or with the .py extension.
 > If we don't want to spend the rest of our lives adding one hack after
 another to deal with Python scripts on Windows, "executing" a Python
 script (via !CreateProcess(), system(), subprocess.Popen() or whatever)
 has to just work, which requires that the .py extension is associated with
 a working Python interpreter.

 Should the existence of a working Python interpreter thus be the
 responsibility of the user? Should we therefore remove the bundled python
 from the wingrass installer? Because we do not want to interfere with an
 existing Python installation, we either do not include an official Python
 installer, or we do, but check first if any Python is already installed on
 the system.

 According to Helmut's report [comment:48] on the registry settings, I can
 not see any trace of the Python versions coming with Inkscape and
 !LibreOffice, but only of the Python version coming with ArcGIS.

 To phrase it provocatively, do we want to go the ESRI way or do we want to
 go the Inkscape and !LibreOffice way?
