inconsistent dll linkage

Greets All...

I'm trying to integrate Opcode Polysoup into stock 1.5.2, using VC++ 2005 Express. I have compiled opcode.dll and opcode.lib successfully. When I go to compile the solution, I get:

------ Build started: Project: Torque Demo, Configuration: Debug Win32 ------

k:\tge_ews\torque sdk\lib\opcode\ice\iceutils.cpp(25) : warning C4273: 'IceCore::Alignment' : inconsistent dll linkage
        k:\tge_ews\torque sdk\lib\opcode\ice\iceutils.h(217) : see previous definition of 'Alignment'

Given that I do my development on OSX and port to Win, I am still unfamiliar with VC++. I'm sure I have not linked the opcode library correctly, can someone explain how to correctly link the Opcode library to the 'Torque SDK' solution?

Thanks
