Thanks sun-managers!
My problem was: my server's syslogd didn't log the messages it
received in any of the files specified in syslog.conf.  This
happened when I upgraded from 4.0.1 to 4.0.3.
Sollution: As most people who answered my call for help guessed,
I had a line "define( LOGHOST, 1 )" in the /etc/syslog.conf.  This
line was apparently added for SunOS 4.0.1, to fix a loop bug in
syslogd.  Since I've removed that line from syslog.conf (and done
a "kill -HUP <syslogd-pid>"), everything works fine.
I think this list is GREAT. I received 6+ replies even before my
question got back to me here in Sweden.  Thank you very much to all
who responded and helped me out!  Here is a list of some of you:
