I'll try that when I get back to this and feed back my results. I figured out
that I can avoid the need for dynamic loading. I wanted to use some existing
extension modules, but the whole point was to use the existing ones which as you
point out are linked against a dll. So even if I created an .EXE that exported
the symbols, I'd still have to rebuild the extensions.
