Setuptools now has a "_distutils_hack" module that replaces the stdlib
"distutils" by setuptools._distutils whenever SETUPTOOLS_USE_DISTUTILS=local
is set. This will become the default in version 50.0.
The stdlib distutils module is deprecated and might be removed in some
future version of Python.

See CHANGES.rst for more changes.
