I don't see how the CFLAGS used in the build process could change > during the test run. 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 Also, be aware that Python 3.3.2 is obsolete. -- Ned Deily, nad@acm.org
