[ns] [Fwd: Error when make nse in FreeBSD 4.4]

[<zhanping@ece.ubc.ca>]

Does anyone have the experience make nse in FreeBSD 4.4. I installed the
 ns-allinone-2.1b8a in FreeBSD 4.4. but when I make nse, it came out an 
error message as follows:

c++ -c -O2 -DTCP_DELAY_BIND_ALL -DNO_TK -DNIXVECTOR -DTCLCL_CLASSINSTVAR

It seems that the problem comes from the #include <netinet/ip.h>. But this 
is the include source code when we install the operating system, there 
should be no error at all. I compile this header seperately and not syntax 
error report. 

Here after is the codes that report error message. 

line
	union ipt_timestamp {
156:            n_long	ipt_time[1];
		struct	ipt_ta {
			struct in_addr ipt_addr;
159:                    n_long ipt_time;
		} ipt_ta[1];
	} ipt_timestamp;

Do you have any idea what can cause this error message?
Thanks for your help.
