Ohh, pardon :) My error: seems that `-fno-warn-orphans` works. Not -W but -f :-)
Hi,
Maybe with -Wno-orphans

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?
