[Python-Dev] internal weakref API should be Py_ssize_t?

I'm wondering if the following change should be made to Include/weakrefobject.h: -PyAPI_FUNC(long) _PyWeakref_GetWeakrefCount(PyWeakReference *head); +PyAPI_FUNC(Py_ssize_t) _PyWeakref_GetWeakrefCount(PyWeakReference *head); And the 2 other files which use this (weakref obj and module). Should this be changed now, wait for 2.6, or not worry about it? n
