a question about style(9) and inline

In looking at lib/msun/math_private, one finds

static __inline float complex
static __inline double complex
static __inline long double complex
static inline double
static inline float
static inline long double
static __inline int
static __inline int
static __inline int
static inline int32_t
static inline int32_t

style(9) seems to not contain any preference with respect
to __inline versus inline.  As a matter of consistency,
I would like to use whatever is the preferred keyword.
So, which should be used?
