Oh, you built with ghcquickbuild? I don't remember the details, but if memory serves it disables a lot of optimisations, etc. just to get GHC built quicker to test that it compiles. So you probably don't want that ;-) -- Ivan Lazar Miljenovic ivan.miljeno...@gmail.com IvanMiljenovic.wordpress.com _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
