//  The author gratefully acknowleges the support of Dragon Systems, Inc., in

//  This file serves as a wrapper around <Python.h> which allows it to be
//  compiled with GCC 2.95.2 under Win32 and which disables the default MSVC
//  behavior so that a program may be compiled in debug mode without requiring a
//  special debugging build of the Python library.


//  To use the Python debugging library, #define BOOST_DEBUG_PYTHON on the
//  compiler command-line.

// Revision History:
// 05 Mar 01  Suppress warnings under Cygwin with Python 2.0 (Dave Abrahams)
// 04 Mar 01  Rolled in some changes from the Dragon fork (Dave Abrahams)
// 01 Mar 01  define PyObject_INIT() for Python 1.x (Dave Abrahams)
