debugging into a DLL with embedded Python

If you do not need to debug into any Python ( .c ) code it is possible to
use the standard release distributions. Put a wrapper around the Python
header in your C/C++ source code:

#ifdef _DEBUG
  #undef _DEBUG
  #include "python.h"
  #define _DEBUG
#else
  #include "python.h"
#endif

I insert a temporary DebugBreak(); statement in my C/C++ source code to
force the Visual Studio debugger to be invoked if running extensions via
PythonWin.

If you want to debug into the Python C source then the above wrapper
technique is not valid. You will need the Python source and the debug
versions of the Python libraries...
