   Use the real python debugging library if it is provided.
   Otherwise use the "documented" trick involving checking for _DEBUG
   and undefined that symbol while we include Python headers.
   Update: this method does not fool Microsoft Visual C++ 8 anymore; two
   of its header files (crtdefs.h and use_ansi.h) check if _DEBUG was set
   or not, and set flags accordingly (_CRT_MANIFEST_RETAIL,
   _CRT_MANIFEST_DEBUG, _CRT_MANIFEST_INCONSISTENT). The next time the
   check is performed in the same compilation unit, and the flags are found,
   and error is triggered. Let's prevent that by setting _CRT_NOFORCE_MANIFEST.

/* We used to try to #undef feature macros that Python.h defines
to avoid re-definition warnings.  However, such warnings usually
indicate a violation of Python's documented inclusion policy:

 "Since Python may define some pre-processor definitions which
  affect the standard headers on some systems, you must include
  Python.h before any standard headers are included."
 (http://docs.python.org/c-api/intro.html#include-files)

To avoid re-definitions warnings, ensure "vtkPython.h" is included
before _any_ headers that define feature macros, whether or not
they are system headers.  Do NOT add any #undef lines here.  */
