fix some -Wsign-compare warnings

[Stefan Huehner]

Hi,

by choosing correct datatypes this patch eliminates some sign-compare
warnings. Should not alter functionality as the variable is initialized
with value >=0 and is only strictly increasing.

ChangeLog:
- fix some -Wsign-compare warnings

Regards,
Stefan
