Description of problem:
Here's a bug in how gcj evaluated method arguments....

public class bug
{
    private static int first (int x, int y)
    {
        return x;
    }

    public static void main (String[] args)
    {
        int l = args.length;

        /* This should print:
0
0
1
        */
        System.out.println (l);
        System.out.println (first (l, ++l));
        System.out.println (l);
    }
}

This is correct output...

[green@build green]$ gcj -o bug --main=bug bug.java -O2 -march=i386 -mcpu=i686
[green@build green]$ ./bug
0
0
1

This is bad output...

[green@build green]$ gcj -o bug --main=bug bug.java -O2 -march=i386 -mcpu=i386
[green@build green]$ ./bug
