Is there a way in c++ to stop more than one instance of a class from being declared within a program?  Ideally I would like to output some #pragma comment to the compiler if this is not the case.

No, you cannot limit the declaration to one single instance. The 'usual' way to go about this is using singletons, see e.g. http://www.codeproject.com/cpp/pdesingletontemplatenomfc.asp ("Thread Safe Singleton Template and Management - No MFC Required!")
