If that expression compiles, then both types are understood by the platform. Because

http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/stdint.h.html

tells us:

    Greatest-width integer types

    The following type designates a signed integer type capable of
    representing any value of any signed integer type: intmax_t

    The following type designates an unsigned integer type capable of
    representing any value of any unsigned integer type: uintmax_t

    These types are required.

we know what that expression evaluates to, no?
