Sorry, the docs aren't complete yet. It turns off the new I/O code which
allows for 'format-based' input/output (eg: date_facet->format("%Y/%M/%d") ).
 Just in case people are dependent on the old I/O facets they can use the
macro to switch back. As a result we are still testing both I/O configurations...

Yes -- this is the one....for now at least.
