ITIMER names

The setitimer(2) manpage lists the #define's
for the ITIMER_* names in the SYNOPSIS.

Is that intended? These are already defined in sys/time.h,
and surely the caller is not supposed to #define them.
In fact, the caller should only use the names,
described in detail in DESCRIPTION, right?
