c++ - Errors when compiling a project with Cygwin -

i'm trying compile project (https://github.com/alfchen/qoetrafficanalyzer) in windows 7 using cygwin. in linux have no problem, need in windows. installed winpcap following steps included here: help installing libpcap on cygwin. however, i'm still having problems. know project uses arpa/inet.h , under windows have use winsock2.h, changing not solve anything. right i'm having following error. hope can me.

be aware of cygwin internal taken bsd , not linux , in case 2 structures not match.
