With the following .ffi file:

(define-ffi-module (libgit2)
  #:include '("git2.h")
  #:inc-dirs '("/usr/include" "/usr/include/git2" 
"/usr/include/x86_64-linux-gnu/"  "/usr/include/linux/")
  #:library '("git2")
  )

I now have the following output:

$ guild compile-ffi libgit2/libgit2.ffi
TODO: compile-ffi args, arrays, extern variables
(unknown):1: parse failed at state 59, on input "__attribute__"
(unknown):1: C99 parse error
