+of other contemporary or modern-day Ada compilers.
+
+Ada/Ed was the first Ada compiler to pass the @acronym{ACVC, Ada Compiler
+Validation Suite} version 1.7 but fails many newer tests and is not a validated
+Ada system.  Being an interpreter, it does not implement most representation
+clauses, and thus does not support systems programming close to the machine
+level.")
