I think I know which ones. These are cryptic error messages. They happened in my case because of the include order. I work under VS 2005 with SP2 (whcih you should install by the way). Make sure you include the system headers (like windows.h) before the boost headers.

VS 2005 SP2? That's strange I cannot find any info about this service pack: http://msdn2.microsoft.com/en-us/vstudio/Aa718359.aspx Tadas
