/* Horrible hack... Please do not look.  Temporary workaround for the
   forward declaration mess of python types (cf vlcglue.h). If we do a
   separate compilation, we have to declare some types as extern. But
   the recommended way to forward declared types in python is
   static... I am sorting the mess but in the meantime, this will
   produce a working python module.
