That's what I'm trying to say; where this message can be issued, 
the operand can be either signed or unsigned and the specific 
interpretation is not part of the semantics for this particular 
operand.  The value at hand is 8 bits, that's all that's known, 
and further smartness from gas would not be appropriate.  There
are no "holes" here.  The test and message is just to catch the
most trivial programmer errors.
