[C++-sig] boost/python 1.33.1 breaks aliasing rules

[Ralf W. Grosse-Kunstleve]

Coincidentally, on Python-Dev Scott David Daniels just suggested this trick to
get rid of the "will break strict-aliasing rules" warnings:

>     PyObject_CallFunction((PyObject*) (void *) &PyRange_Type,
>                           "lll", start, start+len*step, step)

I.e. the trick is to insert an intermediate (void *) cast. It works with g++
4.1.0 at least. Could this be a general solution?
