           Summary: using std.socket and calling ntohl in class member
                    causes link failure
           Product: D
           Version: 2.004
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: major
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: regan netmail.co.nz


Using ntohl from std.c.windows.winsock in a class member while also using
something from std.socket causes linking errors.

//TEST CASE

import std.socket;
import std.c.windows.winsock;

pragma(lib, "wsock32.lib");

class IndexPacketReader
{
    //static void foo()  //works
    void foo()
    {
        ntohl(1);  //fails
    }
}

void main()
{
    new TcpSocket();
    //ntohl(1); //works
}

 Error 1: Previous Definition Different : _ntohl 4
--- errorlevel 1 

Removing the "new TcpSocket()" makes it link.
Making the class member static makes it link.
Calling it from main makes it link.

I have tried removing the pragma and specifying the .lib in the command line,
no change.  I have tried uising ws2_32.lib instead of wsock32.lib, no change.

In my case I wrote my own ntohl to get past the problem.
