[$] Would you like signs with those chars?

Among the many quirks that make the C language so charming is the set ofbehaviors thatit does not define; these include whether a char variable is asigned quantity or not. The distinction often does not make a difference,but there are exceptions. Kernel code, which runs on many differentarchitectures, is where exceptions can certainly be found. A recentattempt to eliminate the uncertain signedness of char variablesdid not get far - at least not in the direction it originally attempted togo.
