Comment (by olly):

 All 4 combinations worked, so I've committed the adjusted patch in
 [165391d49d0e52ae416f0c75350f79fe626311da].

 The bindings needed a small tweak to get SWIG to see
 `XAPIAN_DOCID_BASE_TYPE`, etc but otherwise seem to work, though we
 probably should have a testcase like `exceed32bitcombineddb1` for each
 language to ensure that 64 bit docids actually work.

 I've opened #686 for the related issue of allowing > 32-bit docid values
 to be used in the disk backends.  This requires an encoding change, so
 isn't feasible for the stable backends (chert and older), but we could
 probably do it for glass.

 I also wonder if 64-bit docids would be a sane default, at least for
 64-bit platforms.  Dylan: Have you done any profiling of your patch
 compared to a standard build?
