Newer versions of bison emit a prototype for yyerror void yyerror (const char *); This clashes with some of our old code that declares yyerror to return an int. Fix that in most cases by modernizing yyerror. bfin-parse.y uses the return value all over the place, so for there disable generation of the prototype as specified by posix. binutils/ * arparse.y (yyerror): Return void. * dlltool.c (yyerror): Likewise. * dlltool.h (yyerror): Likewise. * sysinfo.y (yyerror): Likewise. * windmc.h (yyerror): Likewise. * mclex.c (mc_error): Extract from .. (yyerror): ..here, both now returning void. gas/ * config/bfin-parse.y (yyerror): Define. (yyerror): Make static. * itbl-parse.y (yyerror): Return void. ld/ * deffilep.y (def_error): Return void.
