Subject: [PATCH] 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.
