Calling __builtins__ from C API

Try:

#include <Python.h>
void main()
{
	Py_Initialize();
	PyObject* builtinsMod = PyImport_ImportModule("__builtin__");
	PyObject* builtinsDict = PyModule_GetDict(builtinsMod);
	PyObject* someString = PyString_FromString("someValue");
	PyDict_SetItemString(builtinsDict, "someName", someString);
	Py_DECREF(builtinsMod);
	Py_DECREF(builtinsDict);
	Py_DECREF(someString);
	Py_Finalize();
}

AFAIK, the only difference is that with PyRun_String(), it has to run
throught the parser first.
