+Subject: [PATCH] Fix incompatibilities with libxml2 >= 2.12.0.
+
+libxml2 changed the required signature of error handler callbacks
+to make the passed xmlError struct "const".  This is causing build
+failures on buildfarm member caiman, and no doubt will start showing
+up in the field quite soon.  Add a version check to adjust the
+declaration of xml_errorHandler() according to LIBXML_VERSION.
+
+2.12.x also produces deprecation warnings for contrib/xml2/xpath.c's
+assignment to xmlLoadExtDtdDefaultValue.  I see no good reason for
+that to still be there, seeing that we disabled external DTDs (at a
+lower level) years ago for security reasons.  Let's just remove it.
+
+Back-patch to all supported branches, since they might all get built
+with newer libxml2 once it gets a bit more popular.  (The back
+branches produce another deprecation warning about xpath.c's use of
+xmlSubstituteEntitiesDefault().  We ought to consider whether to
+back-patch all or part of commit 65c5864d7 to silence that.  It's
+less urgent though, since it won't break the buildfarm.)
