Please can you submit the fixed version of this as a pull request upstream too, and I'll approve it there so that we don't have more pain merging the next time.

Please keep brace style consistent with the rest of the codebase.

Also, (void) should be ().

I don't see the implementation of any of the methods declared here.

I think you also want the symbols for the bad_array_new_length class (especially the typeid stuff) or you won't be able to dynamic_cast<> it or catch (std::bad_array_new_length).
