Yeah, gcc v7 has a lot more warnings about obsolete behavior. The committee decided that two C++99 features, throw specs and auto_ptr, were irretrievably bad ideas so it's kind of surprising that compilers haven't been complaining about them for longer.

Grep found only that one, and I pushed a commit removing it. If you find more by all means remove them.
