--- Comment #1 from simon at pushface dot org --- I think that "predefined" means something like "System or one of its children", and the message indicates that (as Arnaud told me, probably about 10 years ago) the language that the compiler supports at that point isn't _quite_ Ada. People are building runtimes for all sorts of odd CPUs, so it would help if the phrasing could be better expressed.
