Oops. The 2-way case would be,
#define IS_MULTI(a,b) __and(IS_ENABLED(a), IS_ENABLED(b))

For the 3 way case,
#define IS_SINGLE(a,b,c) (__xor(IS_ENABLED(a), IS_ENABLED(b), IS_ENABLED(c)) &&
!__and(IS_ENABLED(a), IS_ENABLED(b), IS_ENABLED(c)))
#define IS_MULTI(a,b,c) (!IS_SINGLE(a,b,c) &&
__or(IS_ENABLED(a), IS_ENABLED(b), IS_ENABLED(c)))
