        * crc_symtable.py:
        C/C++ code can now be generated for the table-driven algorithm with widths
        that are not byte-ligned or less than 8.
        W A R N I N G: introduced new variable crc_shift, member of the crc_cfg_t
                       structure, that must be initialised manually when the width
                       was undefined during C/C++ code generation.
    2010-03-27
        * crc_opt.py, crc_algorithms.py:
        Python implementation of the table-driven algorithm can handle widths less
        than 8.

        Suppressed warnings of unused cfg structure on partially defined models.
    2010-03-26
