[Hat] 2.05

Malcolm, I'm trying to build hat with ghc 6.6 - I was under the impression that you'd updated it to be compatible, or am I missing something? At the moment I've modified the make files to get rid of the -package {base|lang|util} arguments, but I still get errors re PackedString (because it's been replaced with ByteString for non unicode, and String for unicode). Am I need of rolling back to 6.5, or is there a quick fix? Bob
