Unfortunately always_inline currently is visible outside. Probably a bad idea in
looking back.
Though I find this define a bit weird anyway, since is named the same
way as one of its "components":
#    define always_inline __attribute__((always_inline)) inline
In addition it is inconsistent, e.g.:
#    define attribute_used __attribute__((used))
so attribute_always_inline would be more consistent (although
always_inline is not only an attribute it also includes inline).
