>Description:
        Self-explanatory. Compiles fine with gcc-3.0.4 and gcc-3.3 (20030118)

>How-To-Repeat:
        Compile this function with gcc -O2 -c
        (simplied from a failure in building lcdproc)

void foo(int len)
{
        while (len >= 8) len -= 8;
        if(!len) return;
}

>Fix:
        none
