Why wouldn't an empty exception specification work?  It seems like the
unexpected() call should call terminate() without ever doing an
explicit catch (...).

Of course, this depends on the compiler implementing exception
specifications properly, and since Visual C++ doesn't ("However, if an
exception is thrown out of a function marked throw(), the Visual C++
compiler will not call unexpected" ~
http://msdn.microsoft.com/en-us/library/wfa0edys.aspx ), it might give
exactly what Dave's contact wants.
