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 
documentation: http://tinyurl.com/cyu2d

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

I'll let Jeff handle this one...
