Finishing touch to Ping's changes. This is a patch that Ping sent me but apparently he had to go to school, so I am checking it in for him. This makes PyRun_HandleSystemExit() a static instead, called handle_system_exit(), and let it use the current exception rather than passing in an exception. This slightly simplifies the code.

#include "Python.h"

#ifndef PLATFORM
#define PLATFORM "unknown"
#endif

const char *
Py_GetPlatform(void)
{
	return PLATFORM;
}
