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