    result = false;

Tom,

Thank you for that, it is very interesting. I tried something similar,
but within a single wrapper function:

void ManagedWrapper(bool do_throw) {
  bool e = false;
  try{
    NativeFunction(do_throw);
  } catch (std::exception) {
    e = true;
  }
  if (e) then
    throw gcnew Exception^;
}

This did not work, so I gave up on this approach. Of course in the
real code, there is additional context information that must be
transferred from the native to the managed exception, so something
like this would be quite a laborious solution: perhaps I
might be able to come up with a really horrific macro that creates
the wrappers for me!
