Description of problem:
While trying to compile oldrhino (from JPackage), I ran into a missing method in
libgcj's JTextComponent:  viewToModel(java.awt.Point).

Version-Release number of selected component (if applicable):
libgcj-4.0.0-0.34

How reproducible:
Always.

Steps to Reproduce:
1. Here's an example of a class that uses this:

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Frame;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextArea;

public class Test extends JFrame {
	private JTextArea fileTextArea;

	private JButton getButton;

	public static void main(String[] args) {
		Frame f = new Test();
		f.show();
	}

	public Test() {
		Container contentPane = getContentPane();

		fileTextArea = new JTextArea(24, 80);
		getButton = new JButton("Press me");
		getButton.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				getButtonPressed();
			}
		});

		contentPane.add(fileTextArea, BorderLayout.CENTER);
		contentPane.add(getButton, BorderLayout.SOUTH);

		pack();

		addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				System.exit(0);
			}
		});
	}

	public void getButtonPressed() {
		int position = fileTextArea.viewToModel(fileTextArea
				.getLocationOnScreen());
		System.out.println(position);
	}
}

2. javac Test.java
  
Actual results:
2. ERROR in Test.java
 (at line 47)
        int position = fileTextArea.viewToModel(fileTextArea
                                    ^^^^^^^^^^^
The method viewToModel(Point) is undefined for the type JTextArea

Expected results:
No output.
