UPDATE 3
As people pointed out, Ideone is a little too restrictive, requiring linkage not just object file creation. As this contest is purely in the name of fun, please be honest and specify what you used to get your score. Either use ideone, or use the most vanilla build (all defaults) of gcc 4.9.2 as you can muster. The contest is intended to bring awareness to the awfulness of C++ error messages.
