------- Comment #5 from benoit dot hudson at gmail dot com 2007-11-08 15:35 ------- The fact that the error appears in backward_warning.h is another annoyance, which is probably why the overly long descriptive message is there. Better would be that #include <ext/hash_set> would only report "<ext/hash_set> is deprecated; please use <hash_set> instead." Then the file listed as generating the problem is hash_set included from the user's code, and the message specifically says what's wrong, and the message fits on one line in a standard terminal.
