Well, on some machines supporting signed characters is painful; if the
machine's byte manipulation instructions don't extend the sign bit, a
program with "char" could involve more instructions than one involving
"unsigned char".  (Always using "unsigned char" isn't a fix, either; on
some machines (like the PDP-11), "unsigned char" requires more code than
"char".)  (Our machines all have signed characters, by the way.)
