Aside of the macro mess. This really wants to be conditional on 64/32 but in the same way as we have the different implementations for timespec64. Your patch enforces a useless conversion from and to itimerspec64 even on 64 bit because the compiler cannot map the types. Sigh. timespec64 is a proper guidance here.
