bison bug?????

[Ruud van der Meer]

Hi all,

I am using bison/flex on windows (Visual C++)
gnu bison version 1.25
gnu flex version 2.5.4

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!
