Can't get it to work on CCL 1.11.1 macOS Sierra.
I tried to run it using ccl with SDL2 installed and I recieve the following error:

````
 Error: Unknown field :WINDOW for foreign-record type:
>        #<FOREIGN-RECORD ANON-TYPE-7768 #x302001A7FDCD>
>        Valid fields:
>          :HDC (SDL2-FFI:HDC)
>        
> While executing: #<STANDARD-METHOD PLUS-C::BUILD-REF (SYMBOL AUTOWRAP:FOREIGN-RECORD T T)>, in process listener(1).
> Type :POP to abort, :R for a list of available restarts.
> Type :? for other options.

This is on CCL64 BTW, I also tried running SDL2 to only arrive the same error.
