I had played with the includes from PCH, and could find out that
including <boost/iterator/iterator_concepts.hpp> in the beginning of
sw/qa/extras/ooxmlexport/ooxmlexport4.cxx allows the test to pass. I
couldn't limit the includes further: only including what's included
inside that boost header does not allow the test to pass. But I don't
understand what does that mean (some ODR violation? some missing virtual
overridden function?...), and don't see where to look next. Does someone
have any ideas?

Thanks.
