Today I downloaded Bison 1.75. I will try to use it.

I still need to check this.

Yes I tried this. It is not working. It goes into infinite loop if use
it with #define YYERROR_VERBOSE 1 . Even if I use it alone then no error
is issued for invalid lines & parser terminates.


But if I use
#define YYERROR_VERBOSE 1
#define YYDEBUG 1

alone then it works, but I am getting 2 errors for each invalid lines.
If I remove the 2nd yyerror function call then it works. (please refer
my mail dated 26/08/04 sub 'RE: Query about error recovery in bison')
