Calls to private constructors are (incorrectly) allowed when  creating an anonymous inner class.

; cat X.java
public class X {
    public static void main(String[] args) {
        // new Y();
        new Y() { };  // should be illegal
    }
}

; cat Y.java
public class Y {
    private Y() {
    }
}

; gcj X.java Y.java --main=X

gcj doesn't give an error, whereas Sun's javac does

; javac X.java
X.java:4: Y() has private access in Y
        new Y() { };
        ^
X.java:4: Y() has private access in Y
        new Y() { };
                ^
2 errors

If you switch around which line is commented out in X.main, then gcj correctly
gives an error:

gcj X.java Y.java --main=X
X.java:3: Can't access private constructor `Y.<init>' from `X'.
           new Y();
               ^
