And I would like to know why this patch is needed at all.

1. I fail to understand why this patch is required at all, because I
don't see why __attribute__(packed) should have any influence on the
structs you are trying to pack.

2. __attribute__(packed) is hack and should not be used.

Can you provide an isolated example exposing the problem (Which?) you
are trying to solve?
