/*
 * The next macro places an integer in the first sizeof(int) bytes of a
 * void pointer location. For 32-bit, it is the same as "(void *) i". It
 * is used to solve a problem found during 64-bit testing.  The problem
 * was that for a configuration parameter such as NS_LDAP_SEARCH_REF_P,
 * which is of type INT and has defined default value, an int
 * variable(ns_param.ns_pu.i) defined inside an union(ns_pu) structure, is
 * used to access the defined default value. This requires the default
 * value to be in the first sizeof(int) bytes of the union element.  If
 * just using "(void *) intval" to declare the default value in the
 * following defconfig[] structure, the intval data will be placed is the
 * last sizeof(int) bytes. In which case, when accessing via ns_pu_i in
 * a 64-bit system, ZERO will be returned as the default value, not the
 * defined one.
 *
 * Note since amd64 is little-endian, the problem is not an issue.
 * INT2VOIDPTR will just leave the data (i) unchanged.
