Hello Adam et al,

My Tasking 2.5r2 compiler for C166 gives the following
warnings on the 4.2 code. Basically, they consist of the
following two warning types:

- signed/unsigned type mismatch

In C, a "char" may be both signed or unsigned _based on
the compiler_ implementation. Explicitly define chars to
"signed char" or "unsigned char". The same goes for
#define's: use "U" behind a value to make it unsigned.

- unused function argument parameters
Maybe I should disable this warning myself, but I often
use

if (unused_var);

in order to prevent these warnings.

(See attached file: TCP.err)
