The test is to check that the two separate implementations of sysconfig
in the standard library (don't ask why!), the newer sysconfig and the
legacy distutils.sysconfig, return the same results for certain key
configuration variables, like CFLAGS. It's not the most critical test
in the world. The important point is that the values from the
distutils.sysconfig version are what will be used during C extension
module builds when you install third-party packages and, if necessary,
most of them can be overridden, either in the package's setup.py or by
setting environment variables. Also, be aware that Python 3.3.2 is
obsolete.
