Thank you!  This looks like it may help.

The install appeared to go well.  After the install, from within the Cywin64 Terminal, I see the following 3 results:

I am pretty computer literate, but at this juncture I'm not sure how to proceed.  I've compiled a few programs before (from within Linux), have done some programming in the past, but am in no way "comfortable" or that knowledgeable about it and am officially stuck.

BTDT, IIRC too many Linux dependencies.
Still running NTP from Meinberg:

https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable
https://www.meinbergglobal.com/download/ntp/windows/ntp-4.2.8p15-v2-win32-setup.exe
https://www.meinbergglobal.com/english/sw/ntp-server-monitor.htm
https://www.meinbergglobal.com/download/ntp/windows/time-server-monitor/ntp-time-server-monitor-104.exe

You can download the sources and build the daemon and utilities with 
older VS releases, but Meinberg provides a service installer and monitor 
utility.

With serial driver and PPS DLL, service and other setup tweaking, you 
can run a serial GPS with PPS at Realtime priority and get microsecond 
stability.
