[Cython] libimobiledevice build broken by 0.20b2

[Julian Taylor]

Hi,
libimobiledevice cython file fails to build with cython git head and 0.20b2.
It works with older versions, the bad commit in cython is:
commit db5d5a41b852fa32876688198e3d2d46f12de858
Author: Robert Bradshaw <robertwb at gmail.com>
Date:   Mon Dec 30 22:24:04 2013 -0800

    Fix bug when base classes were declared out-of-order.


its parent commit succeeds the build.


the file is:
https://github.com/libimobiledevice/libimobiledevice/blob/master/cython/imobiledevice.pyx

build can be run with
./autogen.sh
./configure --disable-openssl
make CYTHON=/path/to/cython

Note, I know neither cython nor imobiledevice, Yaroslav Halchenko just
encountered this issue while testing packages with 0.20b2 in Debian.
Let me know if you need more information.
