The only requirements are that EXIT_FAILURE and EXIT_SUCCESS must
"expand to integer constant expressions that can be used as the argument
to the exit function to return unsuccessful or successful termination
status, respectively, to the host environment;" (7.24p4) It's completely
up to the implementation which expressions are used, and there's no
requirement that there be a direct connection between the value passed
to exit() and the numeric value received by the host environment. In
fact, there's no requirement that the status be in the form of an
integer value.

A value of 0 passed to exit() must also result in returning a successful
termination status to the host environment. EXIT_SUCCESS is not required
to expand to an integer constant expression with a value of 0, nor is it
prohibited from doing so.
