libipq with pthreads

[Oumer Teyeb <oumer@cpk.auc.dk>]

Hi,
I have a libipq program that compiles perfectly with this

gcc -g -Wall -Wunused -DNETFILTER_VERSION=\"1.2.7\" -rdynamic -o test 
test.c /usr/local/lib/iptables.o /usr/local/lib/libiptc.a -ldl -lipq

and I wanted to put multithreading features on it and in my system I run 
pthread programs as

gcc  -D_POSIX_C_SOURCE=199056 -D_REENTRANT -ansi -lpthread -o 
test_thread test_thread.c

so I put some pthread functionality in my original pthread program and 
tried to compile with the following

gcc -g -Wall -Wunused -DNETFILTER_VERSION=\"1.2.7\" 
-D_POSIX_C_SOURCE=199056 -D_REENTRANT -ansi -rdynamic -o test test.c 
/usr/local/lib/iptables.o /usr/local/lib/libiptc.a -ldl -lipq -lpthread

but this time I get the error:

 >In file included from /usr/local/include/libipq.h:37
 >from test.c: 2:
 >/usr/include/linux/netfilter_ipv4/ip_queue.h:27: 'IFNAMSIZ' undeclared 
here (not a function)
 >/usr/include/linux/netfilter_ipv4/ip_queue.h:28: 'IFNAMSIZ' undeclared 
here (not a function)
 >/usr/include/linux/netfilter_ipv4/ip_queue.h:35: confused by earlier 
errors, bailing out

I think the problem is with some order of library binding, but I 
couldn't figure it (I tried to link one library before the other and the 
like).
What is wrong?
