Hard problem. Not sure I have an answer. A pragmatic answer for
libstdc++, might be to build/run the old libstdc++ testsuite, linking
with the newer libstdc++.{a,so} and visaversa.
If they are `compatible' then testsuite must pass (to the extent it
passes normally). I think this type of testing would have shown
problems in the past.
Also, this is an intentionally simple idea to get our feet wet with
something that I think is easy enough to do. From there, we can
expand.
