[cl-opengl-devel] errors with cffi changes?

[Charlie McMackin]

Have there been any changes in CFFI recently that causes problems with
cl-opengl? I personally am seeing errors with funcs.lisp that look
like this:

; compiling (DEFGLFUN ("glTexSubImage1D" TEX-SUB-IMAGE-1D) ...)
; file: /home/charlie/opengl/cl-opengl/gl/funcs.lisp
; in: DEFGLFUN ("glTexSubImage1D" TEX-SUB-IMAGE-1D)
;     (CL-OPENGL-BINDINGS::DEFGLFUN
;    ("glTexSubImage1D" CL-OPENGL-BINDINGS:TEX-SUB-IMAGE-1D) :VOID

;    (CL-OPENGL-BINDINGS::LEVEL CL-OPENGL-BINDINGS:INT)
;    (CL-OPENGL-BINDINGS::XOFFSET CL-OPENGL-BINDINGS:INT)

;

Basically this occurs for the 300+ defglfuns in funcs.lisp.
(interestingly the defglexts appear to compile fine) I had previously
been working with cffi+lotsofstuff but recently changed back to cffi
main. I have tested with both darcs cffi and cffi+lotsofstuff on
sbcl+threads 1.0.15 and 1.0.17, each time deleting  .fasls, with the
same results. Has anyone else experienced something similar?
