printf() takes an indeterminate amount of arguments. You can't do that in Ada.
However you can simulate it with a single argument that is an unconstrained
array.

Using that trick, along with some of the tricks and the facilities in gnat's
Spitbol.* packages, I think it'd be doable. Probably not worth the effort, but
doable.

For those of you who haven't taken a look at it, I highly reccomend playing
with the gnat Spitbol packages. There are some rather nifty coding tricks in
there that I had never thought of before. I'm certainly the richer for having
figgured out how to use it.
