Description Ben LaHaise 2003-02-21 16:25:47 UTC
The program below should emit a warning when compiled with -Wall or
-Wsequence-point as a is read and modified.  Also, would it be possible to get
-Wsequence-point enabled by default in gcc?

int foo (int count)
{
        unsigned a = count;
        if ((a -= sizeof(count)) > a)
                return -1;
        return 0;
}
