The rawhide JacORB doesn't build with gcj 4.1 because of incompatibilities between libgcj's org.omg.CORBA and JacORB's org.omg.CORBA. The JacORB code is referring to org.omg.CORBA fields that only appear in the JacORB version of these classes, and there's no way to override libgcj's built-in version at build time. This problem is similar to the xml-commons-apis problem we've discussed here and in bugzilla. AG
