Where online can I find a list of countries meeting the WGS-84 GPS
standards?

WGS-84 is not a GPS standard, but the Earth model for great circle long
range navigation.

It's not that either. It's a mathematical formula for approximating the shape of
the world. GPS and many maps use it.

You might want to see the long range Nav RTCA document. In fact, the
equation is the one used in the FMS and is certainly exactly as I wrote.

RTCA does not define WGS-84.

What RTCA does is apply WGS-84. It is for that reason that some automation
does not operate properly in Countries not using the WGS-84 Earth model.

They may reference or use it in their
standard, but that doesn't really have anything to do with the original
question.

It is the reason for the question, Ron.

While use of the WGS-84 ellipsoid parameters would be handy for computing
great circle numbers, your statement as a whole is nonsense.

Thing before you post, Ron.
