patch applied (cabal-branches/cabal-1.10): "Refactor to avoid problems when $HOME is not set"

Sun Apr 17 08:41:35 PDT 2011 Ian Lynagh * Refactor to avoid problems when $HOME is not set We now avoid calling getWindowsProgramFilesDir and getAppUserDataDirectory when we don't need to know their results. This means that a GHC build goes through when $HOME is unset (GHC trac #5047).
