VC++ giving error messages for CS file.

[Arquinsiel]

When trying to compile a project made mostly from code taken from IsoTest in the standard package I get four errors in ref.h, which I have not modified at all. I presume I've set some dependancies wrong but can't seem to fix it. Where am I being stupid?
The build log is found here: http://www.redbrick.dcu.ie/~tuelean/BuildLog.htm For some reason it won't display properly in firefox for me so you may have to use IE.
