From c6d7d6312c21bbcfb236d48bb7c11cedb234389f Mon Sep 17 00:00:00 2001 From: Andrea Monaco Date: Sun, 12 Dec 2021 10:24:28 +0100 Subject: intl/plural.y: Avoid conflicting declarations of yyerror and yylex bison-3.8 includes these lines in the generated intl/plural.c: #if !defined __gettexterror && !defined YYERROR_IS_DECLARED void __gettexterror (struct parse_args *arg, const char *msg); #endif #if !defined __gettextlex && !defined YYLEX_IS_DECLARED int __gettextlex (YYSTYPE *yylvalp, struct parse_args *arg); #endif Those default prototypes provided by bison conflict with the declarations later on in plural.y. This patch solves the issue.
