I agree.  If we must use symbolic names, I suggest we just follow the
standard, cf. ISO/IEC 9899:1999 =C2=A77.20.4.3:

  If the value of status is zero or EXIT_SUCCESS, an implementation-
  defined form of the status successful termination is returned. If the
  value of status is EXIT_FAILURE, an implementation-defined form of the
  status unsuccessful termination is returned. Otherwise the status
  returned is implementation-defined.

Note that our <stdlib.h> defines EXIT_FAILURE to 1.
