Perhaps NYU will answer your question more articulately than I,
but in fact GNAT does not generate code when a _generic_ (like 
Direct_IO) is compiled. The syntactic and semantic checking is
done, but the code is not generated till the generic unit is
instantiated.

Hmmm - better let NYU handle this one. But the "no code generated"
is a normal GNAT message when a generic is compiled. 

Have you reported this to gnat-report@cs.nyu.edu? If not, please do.
