Hi all,
I am using bison/flex on windows (Visual C++)
gnu bison version 1.25

I made a small parser and I noticed that the define YYFLAG
in my generated cpp file is set to (+)32768. In an example I
found I see it is set to -32768. I wonder how I can also set
it to -32768!
It seems that a result of having this define set to 32768 is
that no additional parser error information is generated. Of
course I like this extra parser error data.
Who knows what I should change (in the .l or .y maybe) to
get a different value for YYFLAG?

PS. I tried this:
%{
#define YYDEBUG 1 // Generate debug code; needed for YYERROR_VERBOSE
#define YYERROR_VERBOSE // Give a more specific parse
%}
and I tried the -t option
but it did not help!
