three_finger_flag - Flag to deactivate the emergency exit key combination. Allegro game programming

       The DJGPP keyboard handler provides an 'emergency exit' sequence which you  can  use  to  kill  off  your
       program.  If  you  are running under DOS this is the three finger salute, ctrl+alt+del. Most multitasking
       OS's will trap this combination before it reaches the Allegro handler, in which  case  you  can  use  the
       alternative  ctrl+alt+end. If you want to disable this behaviour in release versions of your program, set
       this flag to FALSE.
