        directive is read.
        Function {\em insert()} is passed the name of a redefined identifier by
        the {\em idname} argument. The redefinition part is expected in the
        lexical buffer {\em lexbuf}.

        The definition is inserted by increasing the array of {\em DEFINED\_}
        structures, pointed to by {\em defined}, by one element. Then, the {\em
        ident} and {\em redef} fields of the newly created struct are assigned.

        After this, the counter {\em ndefined} is increased.
