Update on C++ support.

I can now compile all the Pyrex programs in directories 1 - 8 of the Pyrex test suite 
as C++. But I would like to do some more rigorous testing of extension types, the 
problem area, before submitting a patch.

I do have one question regarding temporary object pointers. Pyrex has code to 
ensure all such pointers are (PyObject *). I took out that restriction to allow 
temporary pointers to extension types to be of the type of the extension type. This 
simplifies the generation C casts. It appears the compiler originally allowed for non 
(PyObject *) pointers. Does removing the restriction re-introduce some kind of bug? 
I have been chasing down the places in the compiler where explicit casts to 
(PyObject *) are made and replacing them with
 "(%s)" % <target_type>.declaration_code("").
