Good.

Did you get the latest versions of include/IO.hi and include/IO.T.hi?
The last 4 lines should read

    interface ! Prelude
    {-# NEED IO #-}
    newtype {-#  #-} IO a;
    }
instead of
    interface ! Prelude
    {-# NEED IO #-}
    data IO a;
    }
This should fix it.

Don't know.  It looks safe enough to keep it in.
