[xml] warning in make tests actually ok?

[George Hartzell <hartzell kestrel alerce com>]

I've built libxml2-2.5.6 on a Suse Linux box.  When I run make tests,
it mentions to expect warnings about title.xml, but doesn't say
anything about a warning I'm getting in the Xinclude test:

  warning: failed to load external entity "test/XInclude/docs/something.xml"

Is this a valid warning, or an acceptable one from the way that the
tests are set up?
