freebsd stable - Mar 2004 - CLOCK_REALTIME incorrectly in sys/time.h ?

Hi,

When compiling a certain software, I come across following bug in FreeBSD 4.x,
when it wants to check the presence of the definition of CLOCK_REALTIME in
time.h:

     # FreeBSD 4.X incorrectly puts the header into sys/time.h;
     # time.h is required (see pages 45 and 46 in the POSIX standard).

Is it worth fixing this in the next 4.X release ?
How is this in 5.X ?

Regards,
Rob.
