Explicitly use `signed char` or `unsigned char`, rather than ``` signed char k; char k; signed char k; char k; ``` This should have resulted in the same thing; however, note that `REFCC` was never defined, and `common.h` was not included, so the old code in fact tested `char` then `unsigned char`, which are the same. The only difference is that a switch using plain `char` is not tested, but since this is the same as either `signed char` or `unsigned char`, the lack of test coverage seems relatively safe.
