If you can come up with a case where this does happen in
practice, I will continue to consider this patch.

Yes, before send patch I also check two archs(arm-v7 and powerpc e6500), they are aligned.
No one report issue, I think cmsghdr aligned on all archs.

Otherwise, we should make the assumptions that exist explicit
and get rid of all of the code that does that funny alignment
upon the cmsghdr structure.

Do you accept that I remove all CMSG{_COMPAT}_ALIGN of header ?

Thanks.
