hi Andreas, 

the basic problem here is that the personw ho implemented the PPS code
(me) didnt have a true refclock to test...

Netbsd's PPS-API was tested with a test program, and I generated
pulses from another machine; but htey werent accurate enough to try
and turn on the KCBIND code.  Looks like that is what's biting you.

For now, I suggest making sure that options PPS_SYNC gets into a
header file that really is included by sys/dev/ic/com.c, and adding
code to silenlty ignore the KCBIND call.

It should be a no-op on NetBSD, since the only consumer we have is
Dave Mills' hardpps() code.

I will fix this as soon as I get camera-ready copy done for
SIGCOMM2000.  Since my personal circumstances have changed, i'll get a
GPS refclock, as well.
