That keyword exist(ed) for the use with compilers that did not understand the
"using" keyword properly. The example is:
struct Base {
void f();
};
struct Derived : public Base {
using Base::f;
void f(int);
};
Compilers that do not understand the using keyword are no longer supported and
really doubt you have one such old beast.
So, more than likely, you've mis-diagnosed the problem.
