GHC 6.8.1: Non-exhaustive patterns in function vectAlgCase, fixed in HEAD

When building the darcs ndp package (last rev Nov 23), I get this failure. Removing -fvectorise from Bools.hs allowed the package to compile. Indeed, this is fixed in HEAD (everything builds fine). This ticket is just to make sure the fix makes it into the next release.
