I have now seen numerous messages posted to this newsgroup which did not
belong here, however I have yet to see any response whatsoever to this
very valid question about a significant C++ standards issue.

What's the problem?  Is there really such a total disinterest in C++
standards issues by readers of usenet news?  Should this newsgroup
be disbanded due to lack of interest?
