octave-nkf: libinterp/parse-tree/oct-parse.in.yy annotate

annotate libinterp/parse-tree/oct-parse.in.yy @ 19983:bf737d927707

eliminate bison warnings from oct-parse.yy * oct-parse.in.yy: Use YYUSE macro and token declarations to eliminate warnings about unused values in bison rules. Avoid unset value warnings by defining $$ as needed.
