Bug in compatibility mode

[Julien LEMOINE]

Hello,
        there is a bug in yacc emulation mode, the original bug report is 
available 
on debian bug tracking system : 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=134068&repeatmerged=yes

I made a patch for this bug, but I am not sure that it does not create 
another problem.

here is the patch :
diff -bBdNrw -U5 bison-1.33-orig/src/reader.c bison-1.33/src/reader.c

   /* As a Bison extension, add the ending semicolon.  Since some Yacc
      don't do that, help people using bison as a Yacc finding their
      missing semicolons.  */
-  if (yacc_flag)
+  /*if (yacc_flag)

     obstack_sgrow (&action_obstack, ";\n    break;}");
 }

here is the problem description :
$ cat test.yy
%{
#include "stdio.h"
%}

%token PARAMS

%%


ocr: PARAMS {printf("params\n")}  '{' /*...*/ '}'
;

%%


extern char *yytext;
int yyerror(char *err)
{
  fprintf(stderr, "%s at %s\n", err, yytext);
  exit(1);
}
$bison -y test.yy
$gcc -c y.tab.c
test.yy: In function `yyparse':
test.yy:10: parse error before `}'
        
please Cc me replies, thanks.
