/* Note: Divonne actually passes a fifth argument, a const int *
   which points to the integration phase.  This is used only rarely
   and most users are confused by the warnings the compiler emits
   if the `correct' prototype is used.  Thus, if you need to access
   this argument, use an explicit cast to integrand_t when invoking 
   Divonne. */
