9.0 is a bit old to be of any interest ...

In 9.5 and up, I see this in bootparse.y:

%token XFORCE XNOT XNULL

but previous versions have neither that declaration nor any uses of
those symbols. I suspect you tried to back-patch a modern version
of bootscanner.l without also back-patching bootparse.y. Or maybe
you just need to remove and rebuild bootparse.c.
