when we use an overloaded static member function as 
another function's input argument, g++ report "assuming
& on overloaded member functions".

This bug does not appear in GCC3.0, though I haven't seen a
similar bug report before.

#include <stdio.h>

typedef int (*COMPTR) (char*, void*);

class Component
{
  public:

  static int foo(char* str, void* ptr)
  {
    return 888;
  };

  static int foo(int x)
  {
    return -x;
  };
};

class Server
{
  public:
  
  void use(COMPTR func)
  {
    printf("%i\n",func("1234", NULL));
  };
  
};

Server server;

template<class T>
class User
{
  public:

  void call()
  {
    server.use(T::foo);	  
  };
  

};


int main()
{
  User<Component> uc;
  uc.call();
}
