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. |
