So it seams that anything is ok for unsigned but not for signed.
Maybe because all computer gave same answer for unsigned but this is not
true for signed?

 I think it is because it wants to (still) support representations other
than 2s complement.  I think POSIX requires 2s complement, and I expect the
C standard to (eventually) follow suit.
 

Since the mid of the 70s all new machines work all with 2s complement.
There will be never computers with different notations since the 2s
complement makes the circuit design easier.
