So far, Firefox (with msvc 2005) and a couple other apps (one using open watcom) build properly on wine. I'm pecking away at the problems that get in the way (particularly cmd bugs at the moment). If you're trying to build a Windows app on Wine by running your normal Windows build procedure (as opposed to using winegcc), I'd like to hear from you, especially if a bug in cmd or some commandline executable that ships or should ship with wine is getting in your way. Thanks, Dan
