That should be foreign-declare for the whole thing, not foreign-code.
Or use #> ... <# which is shorthand for foreign-declare.
#define FOO -1
Another option is the feature-test egg, which is useful for complex cases,
and doesn't require that you redefine anything.
But for cases where it is safe to #define an undefined macro (in other words,
when you can guarantee there is an impossible, harmless or safe default value),
the above is easier.
