Yes, I read the 4.1.1 docs:
By default, such a bit-field is signed, because this is consistent: the basic integer types such as int are signed types.
That is the whole basis for my argument, when you declare something "int," most programmers would consider that to be SIGNED regardless of whether it is 32 bits, 13 bits, or 1 bit.
No doubt it is configurable because of the existance of brain-dead compilers that treat them as unsigned. - 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/
