 Yes: here is an example (K&R C) of echo.c (this will not win an obfuscated
C contest, but it certainly is perverse!)

  #include <stdio.h>

  main(argc, argv)
  int argc;
  char *argv[];
  {
     if (argc > 0) {
	   	  fputs(*argv, stdout);
		  fputs(" ", stdout);
		  return main(--argc, ++argv);
	  }
	  puts("");
	  return 0;
  }
