Overloaded const Bug?

The program below declares t1::fun() as a const member and t2::fun() as an overloaded
nonconst member. In the main program when "fun()" is called directly everythings
works as I expected. However when "fun()" is call via the member function 
"t1:dave()" "t1:fun()" get called instead of "t2:fun()".
*/

#include <stream.h>

class t1 {
public:
  virtual const char* fun() const;
  void dave();
};

const char* t1::fun() const {cout << "t1:fun()\n"; return NULL;}
void t1::dave() {fun();}

class t2: public t1 {
public:
  const char* fun();
};

const char* t2::fun() {cout << "t2:fun()\n"; return NULL;}

main() {
  t2 a;
  a.fun();   // prints t2:fun()
  a.dave();  // prints t1:fun(). I expected t2:fun() to be printed since
             // a is not a const object.
}
