Synopsis: std::valarray<T>::operator==(std::valarray<T>&) doesn't return bool

State-Changed-When: Wed Feb  6 16:20:57 2002
State-Changed-Why:
    Not a bug. According to 26.3.3.2, operator== returns a
    valarray<bool> *not* a bool. Indeed, this one compiles:
    #include <valarray>
    
    int main(int argc, char* argv[])
    {
      std::valarray<double> a(1.2, 10);
      std::valarray<double> b(1.2, 10);
    
      //bool equal = ( a == b);
      std::valarray<bool> equal = ( a == b);
      //return int(equal);
    }
    
    Cheers, Paolo
