I (somewhere) have a patch for configure that generates the appropriate
tags. OTOH, the fact the tags can't be used to disable include files
(apparently the include is processed first, surprising almost everyone)
makes me less enthusiastic about this. Also, I hope soon to migrate
notmuch from xapian 1.2-1.4 to xapian 1.4-1.6, so everything will have
field processors.
