How to overload operator==() for a pointer to the class?

Question

I have a class called AString. It is pretty basic:

class AString
{
public:
    AString(const char *pSetString = NULL);
    ~AString();
    bool

No, there is not.

To overload operator==, you must provide a user-defined type as one of the operands and a pointer (either AString* or const char*) does not qualify.
And when comparing two pointers, the compiler has a very adequate built-in operator==, so it will not consider converting one of the arguments to a class type.
