    [refer]: Quieten compiler warning.
    
    * src/preproc/refer/label.ypp: Drop redundant declaration of `yyparse`.
      Both byacc 20140715 and GNU Bison 3.3.2 supply the the function
      prototype themselves.  Addresses "-Wredundant-decls" warning from GCC.
    
    Fixes <https://savannah.gnu.org/bugs/?43569>.
    
    Also update editor aid comments; drop old-style Emacs file-local
    variable setting.
