There seems to be a bug in the Rational class of libg++ 2.0.
The following program is compiled with g++ 2.1 on a SPARCstation 1 running
SunOS 4.1.1

Ron Sommeling <Ron.Sommeling@cwi.nl>

% cat t.cc  
#include <iostream.h>
#include <Rational.h>

main() {
  cout << Rational(2,3) << endl;
}
% g++ -v t.cc
