>Environment:
Linux redhat 6.1
>Description:
The gcj 3.1 java.io.File.getParent() does not work as does the jdk1.3.1 version.
It strips the leading '/' in single path components like '/foo'

/local/src/misc>cat FileTest.java 
import java.io.*;

class FileTest {
    public static void main(String args[]) {
        File path = new File("/foo");
        System.out.println("parent=" + path.getParent());
    }
}

/local/src/misc>gcj -g --main=FileTest FileTest.java -o FileTest
/local/src/misc>
/local/src/misc>FileTest
parent=
/local/src/misc>
/local/src/misc>javac FileTest.java
/local/src/misc>
/local/src/misc>java FileTest
parent=/
