And likely unless it has been changed in the last day or so, you'll run
into an error building StdDIS.(l)hs in hslibs/win32.  One solution is to
import GHC.ForeignPtr (newConcForeignPtr) and replace all uses of
newForeignPtr with newConcForeignPtr (a better solution would probably
be to use whatever is appropriate for newForeignPtr, I'd have to reread
the FFI spec to see what that is, perhaps nullFunPtr works (guessing
blindly))
