Hello, Dear List!

I want to turn-off concreate warning (but to have all other, and possible to treat them as errors). This warning is about orphans instances. I tried:

-Wall -Werror -Wno-warn-orphans

also

-Wall -Werror -Wno-warn-warn-orphans

But GHC does not understand this option. How to achieve this?
