Yes.

That happens in bits/timesize.h.

Once bits/timesize.h exists, the value from there can be used in 
bits/time64.h, so only one bits/time64.h should be needed.

This patch could be split in two.  The first would add bits/timesize.h 
(two variants), and maybe also use __TIMESIZE in bits/msq-pad.h and remove 
the x86-specific version of that header.  The second would add 
bits/time64.h (one variant).
