I don't have a copy of VC to hand to test, but I might have tried something 
along these lines:

somheader contains:

class Whatever {
   private:
      void ohnoyoudont(int);
}


My C file:

#define ohnoyoudont blah(){};public: \
inline void sneak(int x){this.ohnoyoudont(x);};private:void ohnoyoudont
#include <someheader>
#undef ohnoyoudont

...
Whatever foo = new Whatever();
int ohyesido = 42;
foo.sneak(ohyesido);

I don't think injecting another couple of non-virtual methods into the 
class ought to break anything.
