Ok, here's simpler code that demonstrates the same problem:

#include <boost/function.hpp>
#include <iostream.h>

void FooBar(boost::function0<void> callback) {
  callback();
}

void CallbackImpl() {
  cout << "Called back ok\n";
}

int main(int argc, char* argv[])
{
  FooBar(CallbackImpl);
  return 0;
}

I'm stuck with Builder because we already have a major system built with 
it (don't look at me, it was coded by Mechanical and Automation 
Engeneers, I was hired later to deal with it, so you can guess the size 
of my problem). I plan on porting it to Visual Studio, but finding the 
time and resources to do that is probably years away. And I probably 
won't be here by then.
