Windows networking code prevents use of -Xlint:auxiliaryclass in jdk build

Some windows-specific java code contains conditions flagged by the javac -Xlint:auxiliaryclass flag, preventing that flag from being used in the build of the jdk repo:

c:\jprt\T\P1\233622.juh\s\jdk\src\windows\classes\java\net\DualStackPlainSocketImpl.java:224: warning: auxiliary class InetAddressContainer in c:\jprt\T\P1\233622.juh\s\jdk\src\share\classes\java\net\AbstractPlainSocketImpl.java should not be accessed from outside its own source file
            localAddress(nativefd, (InetAddressContainer)iaContainerObj);
                                    ^
c:\jprt\T\P1\233622.juh\s\jdk\src\windows\classes\java\net\TwoStacksPlainSocketImpl.java:125: warning: auxiliary class InetAddressContainer in c:\jprt\T\P1\233622.juh\s\jdk\src\share\classes\java\net\AbstractPlainSocketImpl.java should not be accessed from outside its own source file
            InetAddressContainer in = new InetAddressContainer();
            ^
c:\jprt\T\P1\233622.juh\s\jdk\src\windows\classes\java\net\TwoStacksPlainSocketImpl.java:125: warning: auxiliary class InetAddressContainer in c:\jprt\T\P1\233622.juh\s\jdk\src\share\classes\java\net\AbstractPlainSocketImpl.java should not be accessed from outside its own source file
            InetAddressContainer in = new InetAddressContainer();
                                          ^

These warning categories should be cleared in this code so the entire jdk repo can be protected by these javac checks.
