I am writing this e-mail really amused(too many broken commits in the name 
of fixing) and annoyed when I wake up master is broken again! You are

While these are good questions and good to explore, I can't seems to feel 
these questions are deflecting immediate issues, that I feel more important
in this thread.

1. why CentOS 6 catching these missing includes? why not the later 

2. The instance I pointed was changes to includes, which broke on some 
distribution and when pointed out those are not fixed in due time. I call it 
leaving master broken for for others while 'your greatest fix' is pushed.

I am a bit annoyed, because I feel I find Libreswan master broken too often
and get distracted from it. May be that is why I am overreacting a bit:)
I think it is everyone's interest to avoid these, contribute time to wider 
basic testing.

So I am continuing on this thread to remind us how a one line change you 
find greatest may cost time for others when they wake up and want continue 
what they were doing.

Now after venting my feelings, lets look at the new issue.

One could say fix one line and move on:) I guess that is what I going to do 
right after the e-mail.
