Hi, Robert

Thanks for the response!  I am running on linux (sorry I didn't mention
that), so the __stdcall thing doesn't apply then, right?  I'll file a bug.

That's interesting that the thunks are a seldom-used feature.  The
documentation says that they're more efficient AND they're way easier to
use than mono_runtime_invoke.  Is the latter really more popular or is
there a 3rd way that I don't know about yet?
