Compiling a flex generated scanner with g++ with all warnings turned on (-Wall)
produces a warning due to "comparison of integer expressions of different
signedness". This change removes the warning by using the same signedness.
This bug was a regression inherited from upstream flex during the rebase to
flex-2.6.1. The same bug was fixed previously (albeit differently) by commit
a3088c99e8.
