The attached patch includes a Steven Watanabe's proposed
reimplementation of boost::none and a test case
demonstrating the regression from 1.33.1. (1.33.1 passes

I know that it's late in the day for fixes on the 1.34

straightforward usage of a commonly used boost library. I
really do think it needs to be fixed before 1.34 can be
