Hey guys,

I have a class with a friend function and a member function with the same name. Calling the friend function from the member function gives me an error: it looks for <classname>::<function> while the friend function is of course simply <function>.

In this case, MinGW GCC says:

```
\Code\RationalNumber\rational.cpp | In member function `long long unsigned int rational::gcd() const':
\Code\RationalNumber\rational.cpp | error: no matching function for call to `rational::gcd(const long long unsigned int&, const long long unsigned int&) const'
\Code\RationalNumber\rational.cpp | note: candidates are: long long unsigned int rational::gcd() const
```

How do I circumvent this naming collision without altering the function names? Can I tell the rational::gcd() to look for the other gcd without namespaces? Or with some sort of "not in any" namespace?

Here's the relevant code:

rational.hpp

```
class rational {
friend unsigned long long gcd(unsigned long long x, unsigned long long y);
public:
unsigned long long gcd() const;
};
```

rational.cpp

```
unsigned long long gcd(unsigned long long x, unsigned long long y) {
if (x == y) return x;
//Euclidean method
unsigned long long diff;
while (x != 0 && y != 0) {
if (x > y) {
diff = x - y;
x = diff;
} else {
diff = y - x;
y = diff;
}
}
return (x == 0) ? y : x;
}
unsigned long long rational::gcd() const {
return gcd(nominator, denominator);
}
```

Thanks in Advance,

Nick
