The grammar for C (including Draft ANSI features) in appendix B of the 2nd
edition the book _C: A Refrence Manual_ by Harbison and Steele seems to
have a number of bugs in it:


    p. 380  = appears twice in the production(s) for assignment-op

    p. 382  The production for conditional-statement appears twice

            The right-side of the production for const-type-specifier
            should be in the font that indicates a reserved word not the
            font for non-terminal symbols.

    p. 383  There is a missing production:

             declarator-list:
                           declarator
                           declarator , declarator

            The symbol 'name' in the production for
            direct-component-selection should be 'identifier'

            There is a spurious line:

             enumeration-constant = expression

    p. 384  There is only one right-side in the production for
            enumeration-type-definition, which is the concatenation of the
            two given in the book.


    p. 386  The symbol 'name' in the production for
            indirect-component-selection should be 'identifier'

    p .389  The symbol 'name' in the production for primary should be
            'identifier'

    p. 392  The right-side of the production for volatile-type-specifier
            should be in the font that indicates a reserved word not the
            font for non-terminal symbols.


Are there any bugs that I have missed?  Are there better ways to fix the
problems that what I suggested above?
