needed to make the asynchronous DNS lookup mechanism work. (It needs to be able to get/set the transaction ID in the trasport handle so it can deliver a delayed UDP response when a reply is received from a DNS server.) With TI-TPC, the transport handle has changed slightly (what used to be an int is now a size_t) so we need to account for this.
