[Bug java/16701] New: GCJ inlines private constants into other classes

[suvarov454 at users dot sourceforge dot net]

I get a compile error when a class uses a public constant from a different
class, which is initialized with the value of a private constant, which is (in
turn) based on the value of another private constant.

When I use the Sun, MicroSoft, Eclipse, or jikes compilers, it compiles fine.

With GCJ, it says that the first class is attempting to access a private member
of the second.

This error appears in both GCJ 3.3.4 (gcj-3.3 from Debian Sarge) and in the
"java-gui-branch" of GCJ 3.5.  I use ".../gcj -C *.java" to compile to CLASS files.

The error from v3.5 is:
Coords.java: In class `TestCoords':
Coords.java: In method `TestCoords.main(java.lang.String[])':
Coords.java:50: error: Can't access private field `Coords.MASK' from `TestCoords'.
           Integer.MAX_VALUE & Coords.MASK;
                                     ^
1 error

The error from v3.3.4 is:
Coords.java: In class `TestCoords':
Coords.java: In method `TestCoords.main(java.lang.String[])':
Coords.java:50: error: Can't access private field `Coords.MASK' from `TestCoords'.
           Integer.MAX_VALUE & Coords.MASK;
                                     ^
Coords.java:56: error: Can't access private field `Coords.SHIFT' from `TestCoords'.
           ( Integer.MAX_VALUE - Coords.MAX_BOARD_HEIGHT ) >> Coords.SHIFT;
                                                                    ^

I've attached the two source files below.
