add -fspec-constr-count workaround
ghc 7 produces these warnings http://hackage.haskell.org/trac/ghc/ticket/4288 The specialization is enabled by -O2, and the default limit of 3 is there to avoid specialization blowing up binary size. Perhaps that default is a little low? I needed 4 to avoid a warning on Unused.hs, and 5 to avoid warnings on test.hs
