I want to use Win32 sockets. I have taken the steps outlined in the FAQ for doing this.

I cannot get the following code to compile using gcc. 

#define Win32_Winsock
#include <windows.h>
#include <iostream.h>
#include <time.h>


void main(int argc, char *argv[])
{
    time_t t;
    int s;
    struct sockaddr_in a;
    struct hostent *h;
    WSADATA wsaData;

    if (argc != 2)
    {
        cout << "Usage: gettime" << argv[0] << " <host>\n";
        exit(1);
    }
    if(WSAStartup(0x101, &wsaData))
    {
        cout << "Unable to initialize WinSock library.\n";
        exit(1);
    }
    h = gethostbyname(argv[1]);
    if (h == NULL)
    {
        cout << "Cannot resolve hostname\n";
        WSACleanup();
        exit(1);
    }

    a.sin_family = AF_INET;
    a.sin_port = htons(37);
    memcpy(&(a.sin_addr.s_addr), h->h_addr, sizeof(int));
    s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (s == 0)
    {
        cout << "Cannot establish connection: "
             << WSAGetLastError() << '\n';
        WSACleanup();
        exit(1);
    }
    if (connect(s, (struct sockaddr *)&a, sizeof(a)))
    {
        cout << "Cannot establish connection: "
             << WSAGetLastError() << '\n';
        WSACleanup();
        exit(1);
    }
    if (recv(s, (char *)&t, 4, 0) != 4)
        cout << "Unable to obtain time.\n";
    else
    {
        t = ntohl(t) - 2208988800;
        cout << asctime(localtime(&t));
    }
    closesocket(s);
    WSACleanup();
}

It appears to have trouble with lines containing funtion prototypes returning pointers.

Any ideas?
