Re: [PATCH] hurd: take __USE_EXTERN_INLINES into account

[Samuel Thibault]

While working on it, I realized that there were more symbols which were
never exposed, and AIUI it's just by luck that glibc libraries never
made a reference to them, because gcc was by luck always inlining them.

        * hurd/Versions (libc: GLIBC_2.22): Add _hurd_fd_error_signal,
        _hurd_fd_error, __hurd_dfail, __hurd_sockfail,
        __hurd_threadvar_location_from_sp, __hurd_threadvar_location,
        _hurd_userlink_link, _hurd_userlink_unlink, _hurd_userlink_clear.
