[Haskell-cafe] Compiling large code with old machine

Hello I'm using GHC to compile around 700K of Haskell Code generated by HaXml. How I compile this code. My machine is Windows-XP(512MB RAM, 1.5GHz) running GHC-6.8.2. How much time it spend to compile this file? I spent more than 1 hour and it doesn't finished. What flags make compiling fast? I try with -H500m but dont't expect. It is possible GHC running endless cycle at compilation stage? Thanks. -- Don't hug that, Hugs ME! Samuel Silva
