I just successfully built the entire distribution and the entire AFP.
(Isabelle a3c7bd201da7 / AFP 6d199a5)
I also removed the rogue "Euclidean Ring" definition and orphaned
instances in Echelon_Form, but I think that Echelon_Form, Hermite,
Algebraic_Numbers and the related entries are in dire need of a major
cleanup. Echelon_Form/Rings2 in particular contains a lot of interesting
