We actually do so in Make, but strangely only in the stage2 build (see
mk/warnings.mk). It's unclear to me why this is the case. I think the
ideal solution is to add an OPTIONS_GHC -Wno-orphans pragma upstream in
the affected module, although this would require getting code upstream
which is a bit tiresome due it being in darcs.

Cheers,
