void* conversion yields ambiguity upon dereference

Hi,

Consider this program:

    struct Thing {
        operator void* () const;
    };

    struct any {
        template<class T>
        any(T const&);
    };

    char operator*(any const&);

    int main()
    {
        Thing t;
        *t;
    }

This compiles on VC7.1, GCC 3.4 and como 4.3.3.  I'm interested to know
the
result when compiled on CW 9.4, which I don;t have access to. Based on the
Boost
regression reports here, http://tinyurl.com/5wtud,
I am guessing the
compiler
will complain of an ambiguity between 'void operator*(any const&)' and
'operator* (void *)'.

I'm puzzled by this reference to 'operator* (void*)'. Since a void pointer
cannot be dereferenced, why should this dereferncing operation be
considered
during overload resolution?

Best Regards,
Jonathan
