Changes to primops break libraries (was Re: 7.8 Feature window)

Hi Gabor,

I get these errors when building a cabal package: (...) I guess this is related to those changes. Yes, that's because of my patches.

If yes, what to do next? Contact the 'primitive' maintainer? It's just like with any other backwards-incompatible changes in GHC - package maintainers need to fix their packages so they work with the new version of GHC. My patch is expected to break stuff, though in 95% fix should be very simple - add 'import GHC.PrimWrappers'. See wiki for more detail: http://ghc.haskell.org/trac/ghc/wiki/PrimBool#Implementationdetails
