> For Linux glibc ports the __TIMESIZE == 64 ensures proper aliasing for
> __clock_gettime64 (to __clock_gettime).
> When __TIMESIZE != 64 (like ARM32, PPC) the glibc expects separate definition
> of the __clock_gettime64.
>
> The HURD port only provides __clock_gettime, so this patch adds
> __clock_gettime64 as a tiny wrapper on it.
