Yes, these were the same, the official distribution, as far as I know.

Thanks for that background information.

Same has happened with Apple's iOS with a top management change.  <G>

I'm going to try an upgrade on the 3.2.27+ RPi to 3.6.11 and see what 
changes.  I was surprised that using the same NTP source, using the same 
"sudo make install" command, put binary files which I had just compiled 
using make in different locations.  I had hoped that NTP might be 
consistent, but presumably if the underlying OS differs the results from 
"make install" will differ.
