Took a quick peek. The Makefile uses "order only" in three spots. This alone demand make version 3.80 IIRC and Documetnation/Changes says 3.79.1... The "order only" is so rare that Paul Smith once said that coming up with a good example of usage was not easy. For the headers_* stuff I recall when I reworked it I could kill the usage of "order only" there but now it crept back - sigh! Sam
