Currently, fails to build trunk on cygwin.

To fix this, attached patch is needed. Or, like py3k, using following
Py_???_HEAD_INIT (surrounded with bracket) might fix this issue in trunk.

#define PyObject_HEAD_INIT(type)	\
	{ _PyObject_EXTRA_INIT		\
	1, type },

#define PyVarObject_HEAD_INIT(type, size)	\
	{ PyObject_HEAD_INIT(type) size },
