The only solutions are: use the GCC packed attribute, redesign the structures...

It is probably enough to mark the inner structure containing the three byte fields 'packed'. Marking it aligned(1) might also have the desired effect. The outer structure should then be ok. But would need to use a specially named attribute so it doesn't get removed.

This may work with the structures I reported in a previous email, but it is not a good solution for us because we have other more complex substructs that cannot be packed that way.

I think we will simply duplicate the members and avoid substructs in our packets.
