   22-Oct-03    MP      Changed WIN32 winsock include to use winsock2.h to
                        avoid a conflict if sim_sock.h and sim_ether.h get
                        included by the same module.
   20-Mar-03	RMS	Added missing timerclear definition for VMS (from
			Robert Alan Byer)
   15-Feb-03	RMS	Added time.h for EMX (from Holger Veit)
   17-Dec-02	RMS	Added sim_connect_sock
   08-Oct-02	RMS	Revised for .NET compatibility
   20-Aug-02	RMS	Changed calling sequence for sim_accept_conn
   30-Apr-02	RMS	Changed VMS stropts include to ioctl
   06-Feb-02	RMS	Added VMS support from Robert Alan Byer
   16-Sep-01	RMS	Added Macintosh support from Peter Schorn
