In principle, yes. How much control do you have over dll formatting in
FreePascal? My experience has been that Pascal compilers generate
uppercase exported symbols. You'll have to export mixed-case symbols
to work with rev's engine. And I believe, but I'm not sure, that
FreePascal allows you to set the calling protocol to stdcall rather
than the Pascal one (which I can't remember off the top of my head).
At any rate, it's documented in the sdk.
