GeneralDeriving a class from more than one interface Pin

How do you derive a class from more than one interface where two or more of the interfaces have methods with the same name, parameters and return type?

class CSomeClass : public IInterfaceA, IInterfaceB
{
public:

CSomeClass();

// IUnknown
HRESULT STDMETHODCALLTYPE QueryInterface(REFIID riid, LPVOID FAR* ppvObj);
STDMETHODIMP_(ULONG) AddRef();
STDMETHODIMP_(ULONG) Release();

// IIntefaceA
HRESULT STDMETHODCALLTYPE DoStuff(VOID);

// InterfaceB
HRESULT STDMETHODCALLTYPE DoStuff(VOID); <-- Compiler generates an error
};

error C2535: 'HRESULT CSomeClass::DoStuff()' : member function already defined or declared

If its as simple as only having one copy of the function then how do you know which interface the function is serving? QueryInterface() handles this by passing in an IID but the functions I'm dealing with have no such parameters.
