------- Additional Comments From bangerth at dealii dot org  2003-09-28 14:52 -------
Poiters to functions are not pointers, so a generic 
  template <typename T> ostream operator << (ostream out, T* t); 
does not apply. Thus the conversion to bool is performed. 
 
The thing with converting to true: function addresses can never be zero, which sets 
them apart from the value of pointers to data, so the result of the conversion  to 
bool is already known to be true. That's where the warning comes from.
