Sorry, I didn't think it could be an extension (although the behaviour
of g++ in this case seemed logical to me and I've always used it),
will better use '-pedantic' in the future.
So Intel C++ 5.0.4 didn't get it right (if compiled with -ansi Intel reports
an error instead of a warning, but the error is still the wrong
error), but g++ did. Very good, g++-team!
Thank you for your support.
