That's strange.  I compile with exception specifications enabled, and I
never see that warning.  Furthermore, the exception mechanism *mostly* works
as it should.  Is it possible that it's the message and its help that are in
error?  Maybe they just didn't update them when the code changed out from
under them.  One thing that annoys the hell out of me is how MS help
(especially if you have MSDN present) seems to want to shunt you to anything
but what you want, probably on the grounds that it's not the latest and
greatest vaporpoop.  For instance, it's almost impossible to get
context-sensitive help on anything in C or C++ to go to anything but
something that's MFC-related.  I've actually gone to the trouble of editing
the .COL file in MSDN (it's an XML file actually) to get rid of stuff I
don't want to see.
