  * Revisions   :
  *    $Log: gateway.c,v $
+ *    Revision 1.9  2001/10/25 03:40:48  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 1.8  2001/09/13 20:10:12  jongfoster
+ *    Fixing missing #include under Windows
+ *
  *    Revision 1.7  2001/09/12 17:58:26  steudten

  *    add #include <string.h>
