Hi Johan -

Not sure if these warnings are normal or not -- it's entirely possible 
they are because we can't see warnings in the regression system (I 
normally don't test vc locally).  The good news is that VC7.1 passes all 
the date-time regressions so the library should work.  I'll put it on 
our todo list to try and track down these warnings...
