I am writing a CFFI tutorial, to be integrated into the manual when it

Looks great, you write very well!
A few minor notes:
- You suggest UFFI-COMPAT is not complete. Well, it should be
complete (though likely not bug free). It passes all of the uffi-
tests and is known to work with (and find bugs in) a couple of UFFI
libraries.
- (defctype :curl-code :int) -- Hmm, using the keyword namespace for
user-defined types. I'm not sure if it's a good idea. Some people
have also suggested that using the keyword namespace for CFFI types
isn't a good idea either.
- @sc{} looks gorgeous. :D
This tutorial shows the usefulness of foreign-funcall for C functions
with varargs. Lispworks unfortunately doesn't export this
functionality. Martin, I wonder if Lispworks will ever export
something like this or if we could have some clues on how to use
unexported functionality to implement cffi-sys:%foreign-funcall (and
eventually cffi-sys:%foreign-funcall-pointer).
