Jesse Rosenstock 18246278c5 switch2.c: Remove use of REFCC and UNSIGNED_CHARS ...

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.
