[AWS] Compiling hello_world errors

Good to hear!

Because it is probably compiled in debug mode so it ends up with all the
debug information in it. To remove the debug info:

   $ strip hello_world.exe

Note also that also using shared libraries (don't remember if it was
properly supported in AWS 2.3.0) will reduce the executable size. An AWS
hello_world compiled with shared libraries an no debug symbols should be
around 20kb IIRC.

Frankly who would like to build anything without a project file at this
point :) ??? Anyway you can use the generated gnat.adc file (see GNAT
User's Guide about the way to use it) that should be in .build/debug or
.build/release depending on the build model used.
