In busybox project we adopted the usage of -Wundef and we try to minimize usage of #ifdef CONFIG_xxx - each boolean CONFIG_xxx option for busybox is accompanied with ENABLE_xxx #define which is 1 or 0, never "undefined", and we check it instead of CONFIG_xxx. Because if -Wundef, gcc complains whenever we use #if on undefined ENABLE_xxx. -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
