subtraction between unsigned ints

[Teruhiko Kurosaka - Sun Intercon]

Does pANSI defines the datatype of the result of subtraction
between unsigned integers?  Would it be also unsigned?  Then
what would be the result of subtraction of a number from a
smaller number?  I am talking about this situation like:
	unsigned int	u, v;
	long int	x;
	u=3; v=5;
	x=u-v;

Is x guranteed to be -2?
