And exactly where is __attribute__((always_inline)) present?  Only on
GCC, right?  What about Sun C, and other C99 compilers?

And how is an additional function an improvement over extremely trivial
macros, like these:

#define XM_DRAG_REASON(originator, code)        ((code) | ((originator) << 7))
#define XM_DRAG_REASON_ORIGINATOR(reason)       (((reason) & 0x80) ? 1 : 0)
#define XM_DRAG_REASON_CODE(reason)             ((reason) & 0x7f)

?
