    if flag(UseExtensions)
        extensions:     TypeFamilies, GADTs, MultiParamTypeClasses,
                        BangPatterns, TupleSections,
                        EmptyDataDecls
        build-depends:  QuickCheck >=3D 1.2 && < 2.5,
                        fclabels =3D=3D 1.1.*,
                        unordered-containers >=3D 0.2.1.0 && < 0.3,
                        hashable =3D=3D 1.1.*
        CPP-options:    -DUseExtensions

So try "-f-UseExtensions" if you really want that?

Cheers,
