Without seeing the rest of your code, I can't be sure, but try changing
the above to the following:
%code require {
#include <stdio.h>
#include <stdlib.h>
#include "Driver.h"
}
If you don't need the std library includes in your .hh file, you might
move them into a "%code {...}" or a "%code top {...}". See the section
"3.1.2 Prologue Alternatives" in the Bison 2.4 manual for a complete
discussion.

For a list of changes over recent Bison releases, see NEWS in your Bison
distribution. In particular, see the entry "Handling of traditional Yacc
prologue blocks" under the 2.3a heading._______________________________________________
