[Coco] A quote...

[Willard Goosey]

"Characters are considered signed integers on the PDP-11, and unsigned
on the other machines.  This persistance of the sign bit may be
reasonably considered a bug in the PDP-11 hardware which has
infiltrated itself into the C language."

--  S.C. Johnson, _Lint, a C Program Checker_, Unix Programmer's
    Manual Supplementary Documents 1, 4.3 BSD, April 1986
