In gcc 3.3, warning in dead code also occurs in another case. Testcase:

unsigned f(unsigned x)
{
        if (sizeof x > 4)
                return x >= 1ull << 32 ? 1 : 0;
        return 0;
}

yields:
foo.c:4: warning: comparison is always false due to limited range of data type

This is a regression from 3.2.2. [Should I open a new bug for it?]
