It is vital that the structures that are marked packed do not have any padding inserted between the fields. Some compilers do this to give fields improved alignment. If your compiler does not support packed structures (it may support them, just using a different syntax to gcc) then you must also make sure that it does not insert padding into structures (i.e. it effectively packs everything).
