With boost 1.33, date_time uses a totaly new system for streaming IO. We
kept the pre 1.33 streaming code, and tests, in the library. That macro
allows a person to choose which system they want to use. This is all in the

The old tests are dependant on the old code, therefore, they fail to compile
when the macro is not defined.
