<p>The exact same revision can indeed build itself (after all that's what happens during "make all" anyway), but the makefile can't differentiate the revision. For it 3.0.1 of revision A is the same as 3.0.1 of revision B. Thus we only check for the version and there for the previous release. This specific case would thus be a valid reason to use the OVERRIDEVERSIONCHECK=1 parameter that you'll need to pass to make then.</p>
