This completes the implementation of WG14 N2412 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2412.pdf), which standardizes C on a twos complement representation for integer types. The only work that remained there was to define the correct macros in the standard headers, which this patch does.
