-Weffc++ and STL

[Frederick W. Wheeler]

Using pragmas to control the emmission of warnings has been discussed
in the egcs mailing list.  I believe that nobody with the knowhow to
implement this is interested in doing it.  One of the reasons is that
postprocessing options, like the grep I noted, are available.  Also,
the gcc people are very much against pragmas for some reason.
