Details:

Subject: preproc/refer/label.ypp: unnecessary declaration of "yyparse()"

  Warnings from the compiler (PWD=build):


  CXX      src/preproc/refer/refer-label.o
src/preproc/refer/label.cpp:340:5: warning: redundant redeclaration of 'int
yyparse()' in same scope [-Wredundant-decls]
  340 | int yyparse (void);
      |     ^~~~~~~
../src/preproc/refer/label.ypp:29:5: note: previous declaration of 'int
yyparse()'
   29 | int yyparse();
      |     ^~~~~~~


  The used "yacc" is "bison (GNU Bison) 3.4.2"

  "yyparse()" in "label.ypp" is only used, not defined.

  Its declaration can be removed (or commented out with an explanation)
without visible effects on the compilation.

  It gets its declaration and definition in the created file,
"label.cpp".
