Codewarrior 8 and Include Paths

Hello, I'm trying to compile some simple test programs that use Boost Header libraries (no building required), like any, shared_ptr etc. Using CW8, I have a strange problem. When I add the Boost root to the access path, the compiler finds the according boost headers, but inside the config header the Boost lib looks up some headers using this syntax: #include and so on. CW8 then fails to find these headers. If I change to "user.hpp" all works fine (but it fails on the next header in angle brackets). Any help appreciated. Roland
