OK this is stat, and we follow the other 64-bit archs which retain the
pads. So we are OK. I can see why they want some solution to this because
Make is having difficulties with file time stamps on fast machines.

But the patches that Drepper rejected where for msq.h, sem.h, and shm.h
(msqid_ds, semid_ds, shmid_ds). Here the other 64-bit archs removed the
pads an left 64-bit time_t only.

Any discussion about changing these structs?
