>Description:
A main program that merely contains a task type
declaration (but no task object) does not react to
the TERM signal.
OTOH, A main program without any tasking related
declarations reacts normally to the SIGTERM.

Here is the test program:

-- file: sigterm_ignored.adb
with Text_Io;

procedure Sigterm_Ignored is

   task type Freerun;
   -- NB: Only a task TYPE, not even a real task.
   task body Freerun is
   begin
      null;
   end Freerun;

begin
   loop
      text_io.put_line ("Here is the main program.");
      delay 1.3;
   end loop;
end Sigterm_Ignored;
>How-To-Repeat:
gnatmake the test program and start it.
Then try doing a "kill -TERM" on the process and witness
that the program is not terminated.
