The signedness is defined by the C language, except for type "char"
where the implementation gets to choose.  What I don't understand is
why you would possibly care about this.  If you need an unsigned type,
use an unsigned type..

All the integers are twos-complement representations, so knowing the
number of bits (8 bits in a "char", others obvious from "sizeof"),
you should be able to easily compute the minimum and maximum representable
values for each integral type.  For floating-point formats, consult Apple's
Numerics Reference Manual (2nd Edition).

There is no such thing.
