  Although for this particular program it doesn't matter, the
  perfectionist in me balks at having exit() in main(), since exit()
  doesn't destroy objects with automatic storage duration.  Return does,
  though.

     int
     main(int argc, char **argv)
     {
         if (argc == 1) {
             printf("BG - run program at Background priority\n"
                    "USAGE: BG \n") ;
             return EXIT_FAILURE ;
         }
         DosSetPrty(PRTYS_PROCESSTREE, PRTYC_IDLETIME, 31, 0) ;
         return spawnvp(P_WAIT, argv[1], &argv[1]) ;
     }

  As I said, for this program it doesn't matter.
