I compiled Matthew's code with GNAT 3.11p on Windows NT (the public
binary distribution) and got the error :
q.ads:4:14: subtype must be compatible with parent discriminant
gnatmake: "q.ads" compilation error
ObjectAda (same machine) gives no error.
I suspect GNAT has a compiler bug; I'll let Matthew submit it.
