Harlan,

I tried 89.7 on both a 3.0-current and a 2.1.6.1 machine and both
produce the "fcntl(F_SETOWN) fails" message if I configure a local
clock. By setting USE_FSETOWNCTTY in config.h it fixed it on both
systems. I attach a patch to configure.in at the end.

Just a note: The 2.1.6.1 machine does not really have a local clock
attached to it, so I could not verify that it really got time from
that interface. It is also not using the kernel PLL stuff, but
apart from that it is looking ok. It haven't crashed or hanged yet.
(Which I'm happy for because the machine is at work and I would not
want to drive in on a sunday night. :-))
