I am pretty sure that "with text_io;" will only execute the spec
elaboration -- which is why you have to be careful when your
initialization calls functions in other packages, cos the _body_ of
the other package needs to have been elaborated.

This seems odd to me, it's loads easier to let GNAT do its own thing
and not have to worry. I admit that a program of ours that built fine
under 3.09 caused us a lot of grief when we tried to migrate to 3.12
-- so much so that we stayed with 3.09 until we had to port to Solaris
x86, with no possible way of building a 3.09 compiler. I can also see
that if you want portability to other compilers you might have to be
explicit ..
