} Right, but then the same variables are used for str*() functions as you

Yeah, but you can pick the method that requires the fewest casts.  Also,
passing an unsigned char * to the <strings.h> functions on a machine where
char is signed is probably benign, unlike passing a char that happens to
be signed to a <ctype.h> function that doesn't go beyond the ANSI requirements.
You'll probably still get bitten by the second argument to strchr(), etc.
