Bug in bison 2.1

[Wang, Zhen]

Hi,

Bison 2.1 produces the sequence of code as below. Note the line
containing only a ";". This extra ";" causes compiler error because the
body of yyparse() follows "int yyparse()" (right after two #endifs).

Bison 1.875 is Ok.


#ifdef YYPARSE_PARAM
# if defined (__STDC__) || defined (__cplusplus)
int yyparse (void *YYPARSE_PARAM)
# else
int yyparse (YYPARSE_PARAM)
  void *YYPARSE_PARAM;
# endif
#else /* ! YYPARSE_PARAM */
#if defined (__STDC__) || defined (__cplusplus)
int
yyparse (void)
#else
int
yyparse ()
    ;
#endif
#endif
