I am using -Ofast for my builds. I will add the flags you mention when I build RC1. Right now, I have other headaches with RC1. :( One thing I can report is that with RC1 on a Mac, Snow Leopard (64-bit build only), I get a timing of 5 minutes with the same scenario as indicated at the top of the thread, far faster than the timing on Windows (64-bit as mentioned before). _______________________________________________ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list
