Unable to bind TCP socket, errno = 112

[nenova]

In cygwin environment I have version 3.6.0 in use and works fine. I have installed (on the same PC) 3.7.3 version built with "sh build.sh -DUSE_GSL=1 -DUSE_PCAP=0 -DUSE_SSL=1". When I run a script using tcp transport it executes OK in 3.6.0, but in 3.7.3 returns an error:
`$ ./sipp.exe -sf /home/user1/sipp/scripts/uac_Register_TCP_common_port_in_Contact.xml 192.168.1.70:5060 -s 700 -r 1 -l 1 -m 1 -t t1 -p 5063
