    What is "it"? Using EXIT_SUCCESS, using gnulib to ensure that you have 
    EXIT_*, using EXIT_* in general?

"It" = Using EXIT_SUCCESS without using the gnulib exit module.  Isn't
EXIT_SUCCESS part of <stdlib.h> (or something) for a couple of decades now?

Obviously it's no particular problem to pull in the exit module, but
also obviously it is good to minimize the number of modules.
