I have merged the graphic-forms-newtypes branch back into mainline, and thus that branch is obsolete. Now that the CFFI project has merged their newtypes branch[1], it's no longer necessary for us to differentiate between the two flavors -- so we are back to using the mainline CFFI code. The latest CFFI from darcs works for me; please send problem reports to graphic-forms-devel if you encounter problems. -- Jack Unrue [1] The closest to an official statement on the branch status in CFFI that I could find is: http://common-lisp.net/pipermail/cl-opengl-devel/2007-June/000117.html
