That is a "bug" in that release of OpenH323. It is fixed in their recent
CVS. Nothing to worry about.

Indeed, GnomeMeeting 0.96.1 doesn't compile with the OpenH323 release
you are trying to compile it with. The reason is that the API has
changed in-between. I suggest you to use an older version of OpenH323,
or to use the CVS version of GnomeMeeting, or to wait for the next
release in 10 days (approximatively).
