I believe I've heard Dennis Ritchie say that he'd consider making char
unsigned if he had to do it all over again.

Extending this to the rest of the integer types is silly, unless you
stop calling them (e.g.) "int" and make it, say, "nat" instead.  People
have this strange impression that something called "int" should behave
somewhat like an integer, and integers are signed by definition.  (The
difference between natural numbers and integers is the inclusion of
negative numbers.)
