compiler warnings in VC9

[kfriddile@…]

I'm not sure whether to submit this under thread or date_time. Including boost/thread.hpp under VC9 with warning level 4 produces the warnings below. Warnings are not allowed on my project, and rather than wrapping every include of boost/thread.hpp with a #pragma directive, I'd rather these warnings just be suppressed in the code that's causing them.
