Pre-ANSI function declarators which do not declare their parameters have been
removed in C23 and the syntax reused for declaring functions with no parameters
(like C++). GCC 15 defaults to C23, so these declarators may cause compilation
failures. For example:
parse_tab.c: In function 'yyparse':
parse_tab.c:2117:7: error: too many arguments to function 'yyerror'; expected 0, have 1
2117 | yyerror (YY_("syntax error"));
| ^~~~~~~
parse_tab.y:105:6: note: declared here
105 | void yyerror();
| ^~~~~~~
parse_tab.c:2228:3: error: too many arguments to function 'yyerror'; expected 0, have 1
2228 | yyerror (YY_("memory exhausted"));
| ^~~~~~~
parse_tab.y:105:6: note: declared here
105 | void yyerror();
| ^~~~~~~
Explicitly specify the parameters of `yyerror` and `yylex`.
