socket.h fails to compile because of <winsock2.h> inclusion - c++

Question

i am using Netbeans 8.1 IDE with g++ compiler (cygwin) to
build a custome Socket class whose implementation is well defined
in socket.cpp, and declared in socket.h as shown below:
//socket.h
#ifndef SOCKET_H
#define SOCKET_H
#include <windows.h>
#include <winsock2.h> /*Code builds successfully if this line is commented. errors otherwise*/
class Socket {
public:
Socket(){std::cout << "Testing: Inside socket constructor ..." << endl;}
Socket(const Socket&);
virtual ~Socket();
Socket& operator=(Socket&);
void Close();
protected:
Socket(SOCKET s); /*Windows socket handle, defined in <winsock2.h>*/
SOCKET s_;
int* refCounter_;
private:
static bool Start();
static void End();
static int nofSockets_;
};
#endif /* SOCKET_H */
now, i test-drove it like this:
//main.cpp
#include "socket.h"
int main() {
Socket socket;
return 0;
}
Above code built successfully when winsock2.h is removed, error otherwise.
Honestly i am new to the netbeans IDE and i can't understand what am doing
wrong. I Dont know what the IDE requires of me either. i need your help to
debugg this please. Thanks. Here's the error:
