singleton warning

[Michael D. Berger & Rosalie A. Clavez]

Using g++ 2.9.3-5 I got a warning that my constructor is private
and I have no friends.  I am a singleton, and I function correctly.
I blocked the warning with:

        class NoClass;
        friend class NoClass;

Is there a better way?

Thanks,
Mike.
