Both PVA and CA protocols depend on less common features of TCP/IP
stacks which behave slightly differently on Linux vs. Windows vs. BSD.
Over the years, we have identified a set of workarounds for these
"quirks".  Of course this depend on being able to identify which TCP/IP
stack implementation is actually *running*.  A build time check is
not sufficient.

With WSL 1, I was not able to find a reliable way to identify that
this "Linux" host actually has Windows IP stack quirks.

The opposite situation exists with WINE where a "Windows" host
actually has Linux IP stack quirks.  Unlike WSL 1, this situation
can be detected at runtime.

If a certain property can't be detected at run time but needs to be, how
about providing a way to set the property at run time since the user
will know what it should be set to?

Personally, I don't think WSL1 is worth my effort at this point.
However, as I have said.  EPICS is what contributors make it.
