They're probably all "char versus unsigned char" complaints?

There are a ton of them on compilers that care about it; most of
'em in the multibyte support.  While it would be nice to clean up
all that someday, I can't say that I think it's a really profitable
use of time.

One difficulty is that the obvious fix (add a bunch of casts) is
probably a net degradation of the code.  Explicit casts will hide
mismatches that are a lot worse than char signedness, and so
cluttering the code with them makes things more fragile IMHO.
I think an acceptable fix would involve running around and changing
datatype and function declarations; which is much more subtle and
thought-requiring than throwing in a cast wherever the compiler
burps.
