I'm still compiling (about every two weeks or so) new versions of the 
dev branch code and putting them on my server, i.e.:

http://norloff.org/ntp/dev/

and

http://norloff.org/ntp/

for the regular code which is updated less often.

The way I install ntp on new machines is to use the Meinberg installer, 
then replace the actual binaries with those I've compiled myself.

I've just replaced my running version with code I compiled a few minutes 
ago, it seems to behave well:

C:\install\ntp>ntpq -pnc rv
      remote           refid      st t when poll reach   delay   offset 
  jitter

Sorry about the wrapping, the key point is that all my servers agree 
that the local clock is just a ms or two off, this is pretty good, 
particularly since it is less than 5 minutes since I restarted ntp.
