In <sys/cdefs.h>, __inline is defined such that the keyword is removed
if the compiler doesn't support it. I doubt it is possible to compile
FreeBSD which such a compiler, so the whole __inline define now seems
only necessary for backwards compatibility's sake. Since plain inline is
already used in libm, it does not really make sense to use __inline
anymore, in my opinion.
