What is "the wrong thing"? Exit statuses (stati? :) are only eight
bits wide; whether they're "supposed" to be 0..255, -128..127, or 0.127
with the other values machine-dependent, I've never seen specified
And which, if any, of these bits of software are wrong (programs
passing small negative values ot exit, shells treating the exit status
as signed or unsigned or whatever) depends on that.
