My update of NTP was via the ports system. The compiler update to GCC-4.2.3_20080130 also was done via the 'portupgrade' system. One of my other applications requires GCC 4.3 instead of the GCC-3.4.6 that is part of the base system. That was why I mentioned that ntp-4.2.2p4 compiled fine on another computer that was running the base system compiler and not GCC-4.2.3xxx. I will contact the maintainer of the NTP port on FreeBSD and see if he has any insight into why the port configuration was not able to detect that I was running FreeBSD 6 and did not have the POSIX Realtime Option. Thanks for the reply. It gives me (and others) some insight into how things work.
