-/*----- 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.
- *
- * Revision 1.1  1999/10/04 21:40:42  mdw
- * Added background resolver from `fw'.
