I think these warnings are completely bogus and should not be worked
around. Even in the most trivial case of
{
unsigned int foo;
...
if (foo < 0 && ...)
...
}
I would not want to remove the check, because as the code gets moved
around, refactored, reused, whatever, the unsigned int might change into
a signed int, and then you're hosed. It's fine for -Wextra, but not for
the -Wall level.
