cast to bool not done

[Loring Holden]

It seems that a cast to bool is not being done automatically by the compiler
(g++ compiled from CVS sources as of 3 pm EDT, Sun, Sep 12).

Error:
/home/lsh/src/bugs/refptr_bool.C: In function `void test()':
/home/lsh/src/bugs/refptr_bool.C:20: `class REFptr<CamFocus>' used where a
`bool' was expected

Source:
template <class T>
class REFptr {
   public:
      operator T* () const;
};

class CamFocus;
typedef REFptr<CamFocus> CamFocusptr;

class CamFocus {
   protected:
      static CamFocusptr  _focus;
   public :
      static CamFocusptr &cur() { return _focus; }
};

void
test()  
{
   if (CamFocus::cur()) {
   }
}
