My guess is that gcc's change to default to C99 semantics has broken
this code in sys/cdefs.h, despite the comment that says it shouldn't:

/* Ensure that always traditional GNU extern inline semantics are used
   (aka -fgnu89-inline) even if ISO C99 semantics have been specified.  */
#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ >= 2)
# define _EXTERN_INLINE  extern __inline__ __attribute__ ((__gnu_inline__))
#else
# define _EXTERN_INLINE  extern __inline__
#endif
