[Pyrex] lvalue cast problem against GCC 4.0 in 0.9.3.1

[Lorenzo Mancini]

I found another lvalue cast problem with Pyrex 0.9.3.1 vs GCC 4.0.

This is a pyx code that triggers the problem:

------------------------------------------------------------------------
cdef class P:
         pass

cdef class X:
         cdef P a
         def __init__(self):
		self.a = None
------------------------------------------------------------------------

The offending C code follows:

------------------------------------------------------------------------
/* "test.pyx":7 */
/* snip... */
   ((PyObject *)((struct __pyx_obj_5test_X *)__pyx_v_self)->a) = Py_None;
------------------------------------------------------------------------

This patch fixes my instance of the problem.
