this has merit.

to be honest, within copyright (UK and EU), i think you could
reasonably use structure definitions as they are fundamental to the
interaction, not the operation of the code.  this has support, though
it's not been specifically ruled on in court (certainally not that
i'm aware of).  there is a much bigger problem around patents and no
amount of clean room coding is going to avoid those.
 ... having said that, nethier is adding some secondary structure --
that is not how patent coverage works, only copyright.
