On order to compile some python modules I needed the attached patch.
Can the maintainer confirm this? Or Yaakov?

extern __declspec(dllexport) cannot be used as constant during compile-time.
=> "initializer element is not constant"
cygwin auto-import feature get's that right at link-time.

This is needed for the constant (compile-time) resolution of 
PyObject_HEAD_INIT(&PyType_Type) in a typical PyTypeObject struct.

As workaround overriding this in object.h helped also:
