There's nothing to fix, I think you just don't understand how C++
works. Either you've got a using directive for namespace std, or
you're experiencing Argument Dependent Lookup again
(http://en.cppreference.com/w/cpp/language/adl).

Please find a different mailing list or forum to learn how C++ works,
since your questions are not specific to using GCC. I recommend
