The C standard specifies two constants, EXIT_SUCCESS and  EXIT_FAILURE, that may
be  passed  to exit() to indicate successful or unsuccessful termination,
respectively. The value of status in exit(status) may be EXIT_SUCCESS,
EXIT_FAILURE, or any other value, though only the least significant 8 bits (that
is, status & 0377) shall be available to a waiting parent proces. So exit(-1)
return 255.

Use the C standard EXIT_SUCCESS and EXIT_FAILURE to indicate the program exit
status instead of "0" or "1", respectively. In <stdlib.h> EXIT_FAILURE has the
value "1": use EXIT_FAILURE even if the program uses exit(-1), ie 255, for
consistency.
