> So, they should commit to compatibility with apis vended, and if they do, I think we should say 0.14 or later.  This doesn’t mean that we won’t need fixes from time to time or that they will always do this, but generally that is true.  If we (they) deviate from this,_then_  we document the exceptions.  If release after release goes out, with all newer versions not working, then the list of known good versions is best; but, I’d say that something is terribly broken if we had to do that.

It would be good to have a recommended version as well (similar for 
cloog, gmp, mpc and mpfr). If you present me three versions which one 
should I choose as a naive user? Are the versions in the 
contrib/download_prerequisites script the recommended ones?
