[Hat] 2.05

[Thomas Davie]

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
