[AWS] gnatmake works, project file does not

You're right. I was going to do that next ;-) (searching for
"gnat-secure_hashes.ads" that is)
(Before I though this reference was just an expansion of
"g-sechas.ads" made by GNAT.)
Funny that the old way (no project file) is impervious to this kind of dirt.
OTOH, this might provide a good way to overwrite system units.
Anyway, lesson confirmed: always keep your directories clean.
Thanks a very great lot.
