I presume you're using Ada.Text_IO, which is a very large, complex package that 
does lots of things few people ever use, such as counting columns, lines, and 
pages. This is the main reason naive Ada hello-world programs are bigger than 
those from languages with simpler I/O libraries.

Since you're using GNAT, one simple option is to use GNAT.IO rather than 
Ada.Text_IO. That should cause a noticeable reduction in executable size.

You can also import the C fputs function and reduce the size even further.
