[AWS] gnatlink fails with aws hello world example on debian 4.0

[Andreas Schipplock]

Hi,
I'm using Debian 4.0 "Etch" and I installed the following packages:
gnat and libaws-dev

Consider the following example that I copied from the documentation:
http://pastie.org/329687
I created the following project file "default.gpr": http://pastie.org/329693
I am compiling this with: "gnatmake -Pdefault.gpr"
I am getting the following gnatlink error: http://pastie.org/329697

If I compile a simple hello world, it's working just fine as expected:
http://pastie.org/329688

I have no idea what's going wrong here. If you could give me a hand, I
would be happy :).

btw.: the example shown on
https://libre.adacore.com/aws/aws-gpl-2.3.0.html#Callback-procedure
has a small mistake in it. In line 12 it has to be "AWS.Status.URI"
instead of "Status.URI" only.

Thanks in advance!
