Quoting Jack Unrue (jdunrue@gmail.com):
I was still using cffi-061208 and haven't been keeping up-to-date with developments in cffi land. I grabbed the latest from darcs and ran into the same compile error that you did.
I've checked in a fix, please update and give it another try. The compile error is resolved and I'm able to call GFS::OBTAIN-DLL-VERSION-INFO successfully:
Thank you, that works great now!
However, I also tried it with Luís' new-types branch, and that fails with a different error now, something about rectangles not being SAPs.

Of course, since the new-types branch is apparently still experimental, that might not be an issue in graphic-forms at all.
Thanks, David
