[boost] [date_time] USE_DATE_TIME_PRE_1_33_FACET_IO

While comparing regression tests results for Boost.Build V1 and V2, I noted
that some date_time tests fail, and traced this to the fact that V2 does not
define USE_DATA_TIME_PRE_1_33_FACET_IO while compiling the tests.

So, I have a couple of questions:

1. What does the macro do? I could not find anything in the docs.

2. For V2, I have as much as three choices:

   - Add this define to the same sets of tests and in V1 Jamfile
   - Add this define to "project requirements" for the date_time/test
     Jamfile.v2, so it will be applied to all targets
   - Add this define to "usage requirements" for the date_time library, so
     that any executable files linking to date_time will get this define
     set.

   Which option is the best?

Thanks,
