* Small but important fixes needed in existing features:
-** Fix compilation when Xaw3d libraries are present but libxaw is not.
-In new X11 versions, xaw3dg-dev does not depend on libxaw-dev, so the
-latter need not be installed. As a result, all the source files that
-look for include files in X11/Xaw should look in X11/Xaw3d if we are
-using Xaw3d.
