Re: How do I end the program?

Yes, but it isn't pretty.

Take a look at the module: Ada.Task_Identification.

In the main procedure of your program, before entering glutMainLoop save off
the task ID of the environment task.

  env_task_id := Ada.Task_Identification.Current_Task;

When you want to kill the program call:

  Ada.Task_Identification.Abort_Task( env_task_id );

When you kill the environment task, all subordinate tasks are terminated as
well.

With GNAT 3.14p, I get the message:
  Execution terminated by abort of environment task

On the console window of my test program.
