+ * TODO: This typedef is wrong.
+ *
+ * This is due to limitations of cffi.
+ * See https://bitbucket.org/cffi/cffi/issue/69
+ *
+ * For another possible work-around (not used here because it involves more
+ * complicated use of the cffi API which falls outside the general pattern used
+ * by this package), see
+ * http://paste.pound-python.org/show/iJcTUMkKeBeS6yXpZWUU/
+ *
+ * The work-around used here is to just be sure to declare a type that is at
+ * least as large as the real type.  Maciej explains:
+ *
+ * <fijal> I think you want to declare your value too large (e.g. long)
+ * <fijal> that way you'll never pass garbage
