Use PyDict_Copy() and PyDict_Update() instead of using PyObject_CallMethod() to call the corresponding methods. This is not a performance improvement since the times are still swamped by disk I/O, but cleans up the code just a little.

#include "Python.h"

#ifndef PLATFORM
#define PLATFORM "unknown"
#endif

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