    Tests how well setuptools supports PEP-426 environment marker.

    The first known release to support it is 0.7 (and the earliest on PyPI seems to be 0.7.2
    so we're using that), see: https://setuptools.readthedocs.io/en/latest/history.html#id350

    The support is later enhanced to allow direct conditional inclusions inside install_requires,
    which is now recommended by setuptools. It first appeared in 36.2.0, went broken with 36.2.1, and
    again worked since 36.2.2, so we're using that. See:
    https://setuptools.readthedocs.io/en/latest/history.html#v36-2-2
    https://github.com/pypa/setuptools/issues/1099
