   You need to mark the symbols you want exported, or the compiler will   
   assume it's dead code and remove them - they're not visible outside of   
   the current compilation unit, and you never called them...so why keep   
   them!   
      
   The easy solution is to just add __declspec(dllexport) to the functions   
   you want exported. Alternatively, you can make a def file to tell the   
   linker precisely what you wanted.
