There are two things you can do:

1) don't use -Weffc++, it's flawed in many ways and noone's forcing you to use
it

2) don't use public derivation from classes without virtual destructors, the
warning is telling you about a potential problem. If you can't change the base
class, take the hint and don't derive from it.
