Fixed various -Wunused-variable warnings

Some of these the compiler is now able to identify thanks to the previous fixes of -Wmissing-variable-declarations warnings, making the variables static. Others are variables that look useful to inspect in the debugger, and so I just cast to void to suppress the warnings.
