You've got a virtual base class, but you haven't declared the destructor - so
the compiler is giving you a default (and non-virtual) destructor.
You need to add something like:
public:
/* virtual destructor added to appease gcc */
virtual ~Control() {}
To your Control class definition - that'll shut it up without turning off the
warnings. Turning off warnings is bad, fixing them is good.
