The problem is some non-ISO-conformant C++ code which previous GCC versions and other compilers accept, but GCC 4.0.1 rejects.

You can fix this by adding:

class InMemoryDatabase;

at line 123 of backends/inmemory/inmemory_database.h

Also detailed here: ​http://article.gmane.org/gmane.comp.search.xapian.devel/577

I'm hoping to release 0.9.3 today, which will include this fix.

Fixed in release 0.9.3.
