I am using VS.NET 2003 and have a simple program which merely includes the
Boost date_time library. When compiling, I get 4 warning messages about
unsafe conversions. Is there some compiler setting that I can change to get
rid of this warning? Shouldn't I be able to include a Boost library without
getting warnings?
Thanks!
