You make a good case. And I am seeing executables of under 1K on the AVR, 
so it is definitely possible (though without much library or any RTS). 
I haven't tried linker settings or "strip" or other tools to see how 
small an executable I can get on Linux. 

But reducing executable size shouldn't be something we have to work to 
achieve; the tools should do it for us. Randy points out that non-Ada 
specific tools may not be well suited to helping us...
