This is correct for the sources which usually are updated both
(running "make update" in /usr/src).

Such differences can occur if you
	1st - make update
	2nd - build and install world and kernel
	3rd - make update again
	4th - build and install kernel only

It can as well happen if you "make install" for a certain part of
the OS (from the /usr/src tree) only.

An indication of the current version of any part of the OS or the
kernel can be obtained from the $FreeBSD$ CVS tag on a per-file
basis. But note that these don't refer to a RELEASE or STABLE
