class Base {

virtual ~Base() {

};
class Derived: public Base {
public:
int Base() {
return 5;
}
};
int main() {
}
When compiled with -Woverloaded-virtual, this file produces:
../gcc-3.2.2/bin/g++ test-hiding.C -save-temps -Wall -Woverloaded-virtual
test-hiding.C:3: warning: `virtual Base::~Base()' was hidden
test-hiding.C:9: warning: by `int Derived::Base()'
which is certainly not accurate. It is true that int Derived::Base() is hiding the name of the base class inside the class, but this is not the kind of name-hiding that (I think) the warning was intended to guard against; nor is it name-hiding that is likely to lead to an error. I think -Woverloaded-virtual should not give a warning in this case.
