I'm running the raw DCF77 variant under NetBSD/i386 1.1A almost right
out of the box with no problems.  I use the clk_rawdcf.c PARSE driver
to read the PPS signal from a cheap DCF77 receiver, level converted
onto a serial port, and the only change needed was to the section for
NetBSD in the file include/ntp_machine.h, which needs to do:

	#define USE_FSETOWNCTTY

The bit of code that uses it is in xntpd/ntp_io.c, and this #define
will cause it to set the serial port to be the controlling terminal
before doing a fcntl(fd, F_SETOWN, pid) on it.

I would assume that this is a "wrong" solution -- it seems to me that
this makes it impossible to run more than one PARSE clock at a time
with the xntpd, and that's a silly limitation.  I just haven't found
the time to look into it yet...  Meanwhile, I'm doing just fine with a
single refclock, thank you!  :-)
