+ * Revision 1.10 2002/03/07 03:50:19 oes
+ * - Improved handling of failed DNS lookups
+ * - Fixed compiler warnings
+ *
+ * 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.
