note that the build fails because -Werror is passed to gcc. you could avoid those by also using -Wno-strict-aliasing in the CFLAGS. patching the code would obviously be better, but the lines that causes that warning that I've checked are not dangerous, and are false posistives afaict, since those are : (type *)&foo->bar with type beeing a structural type. -- ·O· Pierre Habouzit ··O [EMAIL PROTECTED] OOO http://www.madism.org
