This is an intersting subject and one Im struggling with aswell.
I tried to use a method presented by Matt Lewis on a cdecl .dll
and it doesnt work still if the .dll is designed for call_backs to
your program. Im guessing this might have something to do with
non-reintrant Euphoria. I just dont know.

I hope Robert clears this up in the future...
