// Use the real python debugging library if it is provided.

// 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.
