POSIX wording is unclear here. From common sense point of view:
1) all-time guaranteed results can come only from own formula and return
values can change when the system libraries are changing (it is true for
many other functions too)
2) nobody uses rand(3) nowadays.
But in case you insist, I may just to not MFC this changes.
