why would this matter? This is C code, not C++ code.
My guess is that it matters with picky implementations intended for debugging. The C standard allows implementations to trap when an out-of-range value is converted to a signed integer, and some debugging implementations do that. See, clang's new -fsanitize=implicit-signed-integer-change option for an example.
