Because this structure is not anything special, simply use the cpp
idiomatic way of referencing the object.

Consistently, structures that are packed still have "struct" used in
declarations.  However, this distinction is only clear through its usage
and nothing in the language.  Perhaps a better approach would be
notational naming struct PackedXYZ {};.  However, that can get out of
control quickly.
