It must?  Says who, based on what standard document?

For starters, nobody gets to make any such claims about 
__wait_status_to_int(), because that's an internal implementation detail 
of Cygwin.  If at all, such a claim might be made about WIFEXITED(), 
which is a POSIX standard element.  But POSIX makes no such requirement, 
as far as I could see on short examination.
