Summary: PyLong_AsVoidPtr()/PyLong_FromVoidPtr()

Initial Comment:
These two functions have mutually-recursive definitions 

in the docs (which is to say, none).

Nope.  Guido checked them in 5 years ago, in rev 1.48.  To 

judge from the checkin comment, the code may actually have 

come from Greg Stein.  I don't have time for it, so unassigning.

Something very simple:



PyObject *

PyLong_FromVoidPtr(void *p)

{

#if SIZEOF_VOID_P <= SIZEOF_LONG

	return PyInt_FromLong((long)p);

#else



#ifndef HAVE_LONG_LONG

#   error "PyLong_FromVoidPtr: sizeof(void*) > sizeof(long), 

but no long long"

#endif

#if SIZEOF_LONG_LONG < SIZEOF_VOID_P

#   error "PyLong_FromVoidPtr: sizeof(LONG_LONG) < sizeof

(void*)"

#endif

	/* optimize null pointers */

	if (p == NULL)

		return PyInt_FromLong(0);

	return PyLong_FromLongLong((LONG_LONG)p);



#endif /* SIZEOF_VOID_P <= SIZEOF_LONG */

}

Thanks for asking but the problem is that I don't know what 

they do!
