So it is undefined on systems with no 32 bit type?

Maybe I'm being dense, but I thought that int32_t was just a typedef for a
big enough type for 32 bits.

So on a twos-complement 36 bit machine we might have

    typedef int int32_t;

in which case integer_traits<int32_t>::const_max would have to be 2**35-1.
