mainly unused parameter and unused function
some parameters are indeed used in a debug built, I used the
(void)(param) trick
warnings reported by clang 4
This is a false positive. First time through the loop 'imod3' is always 0
so c1 is not used. It's also set so further iterations have a valid 'c1'.
If 'value' is empty the switch doesn't look at 'c1' either since 'imod3'
is still 0.
