-/*----- Revision history --------------------------------------------------*
- *
- * $Log: bres.c,v $
- * 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'.
