 /*----- Revision history --------------------------------------------------* 
  *
  * $Log: bres.c,v $
+ * Revision 1.5  2001/02/03 16:21:08  mdw
+ * Bug fixes: restore signals to their default dispositions, and set up the
+ * addresses properly when unpacking @hostent@ structures.
+ *
+ * Revision 1.4  2000/08/15 17:35:02  mdw
+ * (gethost, and others): Since @gethost@ actually uses @malloc@ rather
+ * than @xmalloc@, it's wrong to use @xfree@ on the result.  Fixed the code
+ * to use the right freeing function on the right data.
+ *
+ * Revision 1.3  2000/06/17 10:38:35  mdw
+ * Track changes to selbuf interface.
+ *
  * Revision 1.2  1999/10/30 11:28:39  mdw
  * Fix include error, pointed out by Chris Rutter.
