        !             9:  * For USG Unix, define USG; for BSD Unix, don't (see ifdef USG).
        !            10:  * For 4.2 bsd, define V4_2BSD; this will replace the routines
        !            11:  * getwd() and rename() with the corresponding ones in the C-library.
        !            12:  * V4_2BSD also selects different definitions for the macros NCPFN and NCPPN
        !            13:  * (max. number of characters per filename, number of characters per path name).
        !            14:  * Define STRICT_LOCKING appropriately (see STRICT_LOCKING).
        !            15:  * Change BYTESIZ if necessary.
