sure, but building binaries against older headers shouldn't generally produce a broken binary when run under newer kernels. imo there's a reasonable middle ground to be had here. duplicating the entire header base to protect ourselves against things is certainly crazy. it'll be a judgement call every time we run into these things. -mike
