You probably want the -Woverloaded-virtual warning, present for many years.
Additionally, G++ 4.7 implements C++0x explicit override control, so you can
change your derived classes like so:
class A_noconst : public A {
public:
void sayhi() override { /* ... */ }
void saybye() override { /* ... */ }
};
class A_const : public A {
public:
void sayhi() const override { /* ... */ }
void saybye() const override { /* ... */ }
};
This causes the compiler to reject the program:
final.cc:9:8: error: 'void A_noconst::sayhi()' marked override, but does not
override
final.cc:16:8: error: 'void A_const::saybye() const' marked override, but does
not override
