duh...

typedef void (*t_pd_observer)(t_pd *self, int argc, t_atom *argv);

void pd_notify(t_pd *self, int argc, t_atom *argv) {
  self->observer(self,argc,argv);
}

There would be other possibilities but they would be less pdish.

Note that if a t_pd_observer wants to keep arguments for later (e.g. using
a t_clock) they must be copied from one list to another because the
original list may be destroyed by the caller of pd_notify.
