In GCC 2.3.1 defining a friend operator in the class declaration 
no longer works, the linker reports an unresolved external. This 
doesn't happen with GCC 2.2.2.

Example program:

class X
{
public:
friend X &operator + (X &a, X &b)
{
    X *p = new X;
    return *p;
}
};


main()
{
    X a, b, c;
    
    c = a + b;
}
