You presumably want the opposite relationship, so that `-Wdelete-non-virtual-dtor` controls both warnings and `-Wdelete-abstract-non-virtual-dtor` only controls the "abstract" warning.
I took this to be the correct order because disabling the abstract case is more dangerous than disabling the non-abstract case (if you disable the abstract one, you're saying "I don't care how bad it gets, don't tell me about it.").
