 I am trying to compile 1.4.14 bindings for use with python 3.12 in my
 CI/CD pipeline for the Roundup Issue Tracker. We use xapian for one of our
 full text search implementations.

  * OS: ubuntu 20.04
  * gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
  * binding source: https://oligarchy.co.uk/xapian/1.4.14/xapian-
 bindings-1.4.14.tar.xz
  * xapian-core/libxapian-dev from ubuntu 20.04 apt repo


 In addition to some deprecation warnings (that I think also occur when
 building under Python 3.11), we get syntax errors of the form:

 The full log is visible at: https://app.travis-ci.com/github/roundup-
 tracker/roundup/jobs/574465489#L980. Before that line are the
 deprecations.

 Is this build supposed to work the same as for Python 3.10, 3.11?

 Thanks.
