listen 出现10022的问题

以前的一段代码，使用中一直没有问题。
同事简单修改了一下，出现
10022 WSAEINVAL
The socket has not been bound with bind.

#include <winsock2.h>
#include <ws2tcpip.h>
#include <process.h>
#include <winsock.h>
#include <iostream>
#include <windows.h>
#include <fstream>
#include <string>
#include <stdio.h>
#include <time.h>
#include <thread>

using namespace std;

void initializeSockets()
    {
    try{
        logEvents("SERVER", "Initializing the server");
        WSADATA wsadata;
        if (WSAStartup(0x0202,&wsadata)!=0){
            cout<<"Error in starting WSAStartup()\n";
            logEvents("SERVER", "Error in starting WSAStartup()");
        }else{

            logEvents("SERVER", "WSAStartup was suuccessful");
        }

        gethostname(localhost,20);
        cout<<"hostname: "<<localhost<< endl;
        if((hp=gethostbyname(localhost)) == NULL) {
            cout << "gethostbyname() cannot get local host info?"
                << WSAGetLastError() << endl;
            logEvents("SERVER", "Cannot get local host info. Exiting....");
            exit(1);
        }

        //Create the server socket
        if((serverSocket = socket(AF_INET,SOCK_STREAM,0))==INVALID_SOCKET)
            throw "can't initialize socket";

        //Fill-in Server Port and Address info.
        serverSocketAddr.sin_family = AF_INET;
        serverSocketAddr.sin_port = htons(port);
        serverSocketAddr.sin_addr.s_addr = htonl(INADDR_ANY);

        //Bind the server port
        if (bind(serverSocket,(LPSOCKADDR)&serverSocketAddr,sizeof(serverSocketAddr)) == SOCKET_ERROR)
            throw "can't bind the socket";
        cout << "Bind was successful" << endl;
        logEvents("SERVER", "Socket bound successfully.");

        if(listen(serverSocket,10) == SOCKET_ERROR)
            throw "couldn't set up listen on socket";
        else
            cout << "Listen was successful" << endl;
        logEvents("SERVER", "Socket now listening...");
        //Connection request accepted.
        acceptUserConnections();
    }

    catch(char* desc)
    {
        cerr<<str<<WSAGetLastError()<<endl;
        logEvents("SERVER", desc);
    }

    logEvents("SERVER", "Closing client socket...");
    closesocket(clientSocket);
    logEvents("SERVER", "Closed. \n Closing server socket...");
    closesocket(serverSocket);
    logEvents("SERVER", "Closed. Performing cleanup...");

    WSACleanup();

}

发现删除#include .，就没有问题。基本就可以确认，引入thread的使用，socket调用bind函数时，使用std::bind()
，而不是winsock的bind，只要在bind加上::,引入全局域作用符即可。
