The issue for the lexical_cast user is that his code will break when Math 
drops C++03 support, and the whole point of the message is to communicate 
this.

The message is supposed to be verbose and annoying, because otherwise nobody 
will pay any attention to it. Sure, the user has no immediate recourse; he 
can only apply pressure on the lexical_cast maintainers to deal with it 
somehow. But again, if there's no message, nobody will care.
