I'm currently developing an SDL app on both Linux and OS X.  To keep
the same source file usable on both platforms, I add

  -feature compile-sdl

to the csc options in the Makefile, then in the main function I do

  (cond-expand
    (compile-sdl
     (declare (foreign-declare "#include \"SDL.h\"\n"))
     (foreign-code "SDL_Init(SDL_INIT_EVERYTHING);"))
    (else
     (sdl-init sdl_init_everything)))

and that way on Linux I can either build the project or just run
./myapp.scm as a script (handy for testing quick changes), and on OS X
I just always build the binary.
