[boost] [1.34.0] date_time and msvc-7.1_stlport4

Jeff, the date_time library has four failures for msvc-7.1_stlport4. http://engineering.meta-comm.com/boost-regression/CVS-RC_1_34_0/developer/da... There are some existing markup for that configuration for related tests, but not for the failing ones. I suppose that the markup should be changed to include those tests too, but that's just a guess. Would you be able to take a look and adjust markup is that's the right thing to do? Thanks, Volodya
