Octal constants are written with the first digit zero.  The following
program

    main()
    {
	printf("test number is %d\n",01234567);
	printf("reverse is 0%o\n",342391);
	exit(0);
    }

produced the following output using cc on my Sun Sparc IPC running
SunOS 4.1.1 and should produce identical output on any 32-bit int
implementation of C:

    test number is 342391
    reverse is 01234567
