+ * Revision 1.6  2001/06/22 19:33:38  mdw
+ * Hack if there is no @_SC_OPEN_MAX@ or @OPEN_MAX@.
+ *
+ * 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
