  * Revisions   :
  *    $Log: jbsockets.c,v $
+ *    Revision 1.20  2001/11/16 00:48:48  jongfoster
+ *    Enabling duplicate-socket detection for all platforms, not
+ *    just Win32.
+ *
+ *    Revision 1.19  2001/10/25 03:40:47  david__schmidt
+ *    Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ *    threads to call select() simultaneously.  So, it's time to do a real, live,
+ *    native OS/2 port.  See defines for __EMX__ (the porting layer) vs. __OS2__
+ *    (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
  *    Revision 1.18  2001/09/21 23:02:02  david__schmidt
  *    Cleaning up 2 compiler warnings on OS/2.
