OK, let's be precise. The relevant standard here is the Single Unix
Specification. SUS v2 mentions only _exit and that is what is more
widely implemented. _Exit exists as well for C99, but it is irrelevant
to mention as the POSIX standard has already _exit and that should be
used in portable code instead.
