dont include both
Why we won't fix this? There is a clear description for the purpose of patch in linux-headers-2.6.30-r1, so we don't care the reason there? For me, I use one socket option IP_TRANSPARENT in my program. This option is for linux only at present, so after upgrade linux-headers to 2.6.36.1, the program failed to compile. The only solution for me is to not include linux/in.h but define the option myself, this is obviously not a portable solution. Also, I see there are several other socket options are linux specific, the program use those options will face the same problem.
take it up with lkml
