C++ abstract class without pure virtual functions?

Question

I have a base class

class ShapeF
{
public:
    ShapeF();
    virtual ~ShapeF();

    inline void SetPosition(const Vector2& inPosition) { mPosition.Set(i

If your compiler is Visual C++ then there is also an "abstract" keyword:

class MyClass abstract
{
    // whatever...
};

Though AFAIK it will not compile on other compilers, it's one of Microsoft custom keywords.
