  Issue 2975: when compiling multiple extension modules with visual studio 2008
  from the same python instance, some environment variables (LIB, INCLUDE)
  would grow without limit.

  Tested with these statements:
      distutils.ccompiler.new_compiler().initialize()
      print os.environ['LIB']
  But I don't know how to turn them into reliable unit tests.
