[Python-apps-team] Bug#682652: Bug#682652: cython: Cython might cause problematic code when trying to build using gcc-4.7

[Andreas Tille]

Hi Yaroslav,

thanks for the upload and the information.  This will enable us
uploading python-biom-format at least to experimental.  It would be
really great if you could also drop me a note once version >= 0.17 would
be moved to unstable to let this package also migrate to unstable.

Have a nice weekend

     Andreas.
