If C is so evil why is it so successful?

  There's this

        Somebody asked about OpenVMS. I haven't used it in a long time, but
        as I recall odd status values generally denote success while even
        values denote failure. The C implementation maps 0 to 1, so that
        return 0; indicates successful termination. Other values are passed
        unchanged, so return 1; also indicates successful termination.
        EXIT_FAILURE would have a non-zero even value.

  And certainly VMS is on topic for this list.
