[cffi-devel] ECL and foreign-symbol-pointer

I have a report that ECL (at least on win32) throws an error if foreign-symbol- pointer does not find the specified function. The docs state that NIL should be returned in this case. This makes use of lispbuilder-sdl problematic on ECL as I make extensive use of foreign-symbol-pointer to detect at runtime if functions in the SDL_gfx, SDL_image, and SDL_ttf libraries are available. Is this something that needs to be fixed in CFFI or ECL? Thanks, -Luke
