I wrote a patch for 3.0.8 that fixed two warnings about macros that got redefined on HP-UX. I did test it on 11.00 and there it works fine, and assumed that it would also work on all 11.X versions. I was sadly mistaken :) On 11.11 (11i) my patch makes TCP_NODELAY disappear as a legal socket option. I'm fixing this as we speak and will submit it after I've tested it on 11.00, 11.11, 11.22 and 11.23 (I.e. all versions of HP-UX including and after 11.00)

Looking at old bugs: fc84e916f628b4fb6f6667ad45d0ced0e9134b23 is still present in the new copy of nis.h created in c29d087e1ea4c92717ef86e372fe80f410580fdc so I think this is still a real bug, even if the problematic systems are likely long dead....
