The following code is ill-formed according to the standard, but accepted by
GCC:
namespace A {
extern "C" void f(int = 5);
}
namespace B {
extern "C" void f(int = 4);
}
using A::f;
using B::f;
int main() {
f(3); //OK
f(); //ERROR
}
When a default argument is used as in the second call, it needs to be looked up
to make sure it isn't declared twice. If it is, then it's an error. GCC will
also accept the code whether the default arguments to f() are given the same or
different values.
