I've checked, and I think Alex failed to update the version.

gcc version 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9)
It also seems to go wrong with g++-3.4 and g++-3.3

Just realised I'm being a bit silly - the error is because I compiled
Xapian without the in memory database. That in turn was because I got
the below errors when compiling xapian-core-0.9.2.

They look like things g++-4.0 is being fussy about. If I add
"class InMemoryDatabase;" just above the class definition 
    class InMemoryPostList : public LeafPostList {
backends/inmemory/inmemory_database.h, that seems to fix it.
