>Description:
The compiler fails to find the (non-template) friend
operator defined in a template class when it is applied to
an object obtained by dereferencing a pointer.

When the friend is a template, the problem disappears.

The same error occurs in gcc-20001002.
>How-To-Repeat:
template <class T>
struct S
{
    friend bool operator== (const S&, const S&) {
        return true;
    }
};

int main ()
{
    S<int> s;
    s == s;   // okay

    const S<int> *p = &s;
    *s == *s;   // error
}
