It seems to me you can get the desired functionality in the Makefiles

Order dependencies are the wrong solution: for one thing, they don'tallow for building just a single front end, which I do all the time.And rebuilding, say, the Fortran front end shouldn't mean that we thenneed to rebuild the Java front end as well.
