   9 //  This file serves as a wrapper around <Python.h> which allows it to be
  10 //  compiled with GCC 2.95.2 under Win32 and which disables the default MSVC
  11 //  behavior so that a program may be compiled in debug mode without requiring a
  12 //  special debugging build of the Python library.
  13
  14
  15 //  To use the Python debugging library, #define BOOST_DEBUG_PYTHON on the
  16 //  compiler command-line.

  18 // Revision History:
  19 // 05 Mar 01  Suppress warnings under Cygwin with Python 2.0 (Dave Abrahams)
  20 // 04 Mar 01  Rolled in some changes from the Dragon fork (Dave Abrahams)
  21 // 01 Mar 01  define PyObject_INIT() for Python 1.x (Dave Abrahams)
