[Boost-users] Problem including hpp Headers

Hello! I´ve installed Boost Libary 1.34.0 I´m working with VS 2005 SP1. If I try to include any of the boost *.hpp files I get more than 100 errors in the files "memory" and "algorithm". I think this errors first occoured, after installing SP1 for VS. Does anyone has any idea why this errors occour?
