[유준희]

I found below error on 90fd35c3a726e613e36ea0399507778b094181a0 with OS X
11.5 (El capitan)

$ make TARGET=generic

make: *** [src/connection.o] Error 1

The reason why is 'struct tcphdr' in <tcp.h> doesn't have source and dest
member:
------------------------------------------------------------------------------------
<tcp.h>
...

81 struct tcphdr {

82 unsigned short th_sport; /* source port */

83 unsigned short th_dport; /* destination port */

84 tcp_seq th_seq; /* sequence number */

...
------------------------------------------------------------------------------------

After I patch, it complied and seems like working properly.
I check the functionality with very simple configuration.
------------------------------------------------------------------------------------

global

        maxconn    10


defaults

        mode http

        timeout connect 5000ms

        timeout client 50000ms

        timeout server 50000ms


frontend http-in

        mode http

        bind *:8080

        default_backend servers


backend servers

        balance    roundrobin

        server     server1 127.0.0.1:8081

        server     server2 127.0.0.1:8082

        server     server3 127.0.0.1:8083
