From 128b2e9569342adb6a230c39530c1386a24d423c Mon Sep 17 00:00:00 2001

Subject: Merge schwarze@'s work for 64-bit types.  This is based on a tweaked
 patch submitted to tech@ on 16/11/2011, 01:39.  It has been updated to
 account for the logical-operator functions and to avoid keeping a live
 pointer into the DBT value, which is not guaranteed to be consistent across
 calls into the bdb library.
