defcfun is confused by typedef of struct as return type w/cffi-libffi

[3b]

(asdf:load-system 'cffi-libffi)

(cffi:defcstruct .foo)

(cffi:defctype foo (:struct .foo))

(cffi:defcfun foo (:struct .foo))
=> OK

(cffi:defcfun foo foo)
=>
; Undefined function:
; :STRUCT
; Undefined variable:
; .FOO
expected same as with (:struct .foo)

tested on sbcl linux and windows, with cffi from ~2014 and 066a38140e9569f04dc9813cb0c6bcfca4075e6d (a few commits past 0.15)
