Warning about passing a signed int to a function that expects an unsigned int,
or vice-versa does not seem like a useful warning to me. On a Linux kernel
build,
% zgrep -c 'differ in signedness' 2.6.10rc2-gcc4-warnings.gz
6809
This is quite high and drowns out many warnings that are more useful.
My understanding is that these warnings only turn into actual bugs on machines
that don't use 2's complement, and I'm not aware of a gcc port to any 1's
complement or sign-magnitude machines. So could this warning be moved to -W
please?
