Subject: [PATCH] Use fixed-size integers for the on-disk pack structure.

Plain integer types without a fixed size can vary between platforms.  Even
though all common platforms use 32-bit ints, there is no guarantee that
this won't change at some point.  Furthermore, specifying an integer type
with explicit size makes the definition of structures more obvious.
