You should be able to do padding just by inserting fields of the
correct type, the same as the C struct does.

Declaring one struct to handle both 64bit and 32bit might be
difficult, but this is ruby, so you can just choose which one you want
at start time (based on the FFI::Platform info, perhaps), and then
always use that one.
