Well, I don't wanna be idiot, perhaps I am too tired, but n_long appears 
in ip.h defined as :

beast# grep ipt_time /usr/include/netinet/ip.h
        union ipt_timestamp {
                n_long  ipt_time[1];
                        n_long ipt_time;
        } ipt_timestamp;
beast# grep ipt_time /usr/include/netinet/*
/usr/include/netinet/ip.h:      union ipt_timestamp {
/usr/include/netinet/ip.h:              n_long  ipt_time[1];
/usr/include/netinet/ip.h:                      n_long ipt_time;
/usr/include/netinet/ip.h:      } ipt_timestamp;
beast#

And, I simply don't find where ipt_time is defined ! I suppose it is 
structure, perhaps it is of type ipt_timestamp, *g*.
And yes, those are all the files I include, nothing more, nothing less.
