Return compiler version, or None if compiler is not available.
Parameters
----------
force : bool, optional
If True, force a new determination of the version, even if the
compiler already has a version attribute. Default is False.

The list of status values returned by the version look-up process

in `ok_status`, None is returned. Default is ``[0]``.
Returns
-------
