__extern_inline  doesn't work with all compilers.  I checked
all user-visible glibc header files with inline functions.  They
are declared with static __inline, __extern_always_inline or
__extern_inline.  None of them use __attribute__ ((__unused__)).
If static __inline should be changed, I believe it should be done
with a separate patch.
