"only"?

    Obsolescing K&R Function Declaration Style

    The K&R function declaration style in the form of

    func(n, m) /* return type is unspecified */
    int n; double m; /* function parameters */
    {
     /*function body*/
    }

    was used in K&R. It was later replaced by the more common form:

    int func(int n, double m) 
    {
    /*function body*/
    }

    The K&R function declaration style is obsolescent in C99. This means
    that compilers are allowed to reject such code or accept it with a
    warning message. In either case, they aren't allowed to ignore it.


Compilers are not allowed to accept this style of declaration without
warning.  They are free to reject it completely, however.
