I forgot about the XAPIAN_AT_LEAST macro. Nonetheless, I'm not keen to
ship untested/uncompiled code (no matter how "obviously correct" it is),
so I'd prefer to wait until Xapian 1.4.6 actually exists before adding
an ifdef like that. FWIW I doubt that the performance impact of passing
1 instead of 0 here is measurable. For me, getting a bug fix release out
is a matter of some urgency; fine tuning and testing against xapian
1.4.6 can wait.
