Hi, Martin Sorry, after trying (fli:size-of '(:long :long)), I found that my LispWorks already support long-long foreign type. I think I should just remove cffi-features:no-long-long feature in cffi-lispworks.lisp, at least for my personal use.
By the way, with some trivial changes, I can compile the whole iolib package (heavily depends on cffi) in amd64 lispworks now. Thank for point out this.
