I use the ActivePython distribution. They are likely to provide 
different binaries, headers should be the same.

I did not do that (but you already know).

I did not set this flag, I just selected only the python bindings to be 
built.

I did not have the issue with GCC.

I put _xapian.pyd, cygxapian-8.dll in lib/site-packages directly. I do 
not think it will make much difference.

I did not have any problem with long long but somebody else did in 
another mailing-list thread which I think I quoted. I managed to build 
the xapian python bindings on at least 2 different WinXP hosts, both had 
development environment setup which makes configuration side-effects 
harder to track.
Your issue may be related to your python distribution (which is probably 
what Olly was referring to when talking about runtime discrepancies and 
what I did not get at first sight). Maybe you could give a try to a pure 
Windows ActiveState distribution with mingw, just to know whether my 
how-to is actually relevant to other people.

Hope this helps.
