I think a bit overprotective here :) At least this = particular warning knob should probably be turned off. Actually, I would rather fix the code that does this than disabling the = warning. Even if this particular code is not vulnerable to format string = problems, it's 2010 now and it doesn't hurt to add a "%s" there. Regards, -- Rui Paulo
