I've been looking for an example in the RTEMS source but haven't been able
to find one.  Maybe it's there but I am just missing it?

Here is the source file I'm attempting to compile:

with Ada.Text_Io;

procedure hello is

  package Text_io renames Ada.Text_io;

begin
  Text_Io.Put_Line( "*** WELCOME TO RTEMS ***" );
  Text_Io.Put_Line( "From GNAT/RTEMS" );
  Text_Io.Put_Line( "***" );
  delay 5.0;
end hello;

When I try using i386-rtems-gnatmake hello I get a bunch of error messages:

I may just need to add some arguments to my gnatmake command.  An example
