Actually I would put all tests into the .setup script (there is an undocumented
`test-compile' function in chicken-setup.scm, which might come handy)
and invoke the makefile (or use the make macro right inside the .setup script)
with the proper `-feature' options. That way one could also build an sdl
extension with support for all those extra libraries that are installed
(like SDL_image, SDL_net, etc.).
