real_zerop thinks -0 == 0

Hi,
The following seems to fix a couple of the remaining Mauve failures (the
mauve tests are first compiled to byte-code).

This isn't a real solution, but I don't know how to correctly test for
positive zero and I really must get some sleep now. Maybe someone more
familiar with this code can suggest the proper solution.
The example code to try is:
public class Z
{
 public static void main(String[] args)
 {
 System.out.println(-0.0f);
 }
}
Compile with gcj -C and run with gij. Output should be -0.0.
Good night,
Mark
