I don't see it other then when someone uses a variable of another type and the "boolean" variable (now an int) is of a larger value then that variable. But then that is a bug and should be fixed. But rest easy, bool will only be _Bool from now on. :) > -- > Lgb Richard Knutsson - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
