Well, OK, but there's lots of things gcc could warn about. How about while (1) { ... By your argument gcc should warn that '1' always evaluates to true. Or how about #if 0 why shouldn't the preprocessor warn that the conditional is always false? > No, shutting gcc up wouldn't be the right thing, IMHO.

OK, but suppose I looked at it and there's no bug. Leaving the warning has a cost too: it hides useful warnings (that might be showing real bugs) in all the clutter. - R. - 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/
