I doubt that it's practical to add the warning that Matthias suggests in
any event.  You could put a #warning in every header that is purely
C++0x, but it would be hard to put warnings in every function that was
added for C++0x.  And, it's reasonable for the library implementors to
use C++0x functionality in implementing C++98 functionality, if that's
convenient.  So, I don't really see how to win here.
