[kaffe] some IPv6-related problem?

Today's regression tests showed:

FAIL: UDPTest.java
FAIL: SoTimeout.java

Let's look into the case of SoTimeout.java. SoTimeout.fail says:
java.lang.IllegalArgumentException: Bad port number: 65536
   at java.net.InetSocketAddress.<init> (InetSocketAddress.java:71)
   at java.net.ServerSocket.<init> (ServerSocket.java:175)
   at java.net.ServerSocket.<init> (ServerSocket.java:149)
   at java.net.ServerSocket.<init> (ServerSocket.java:130)
   at SoTimeout.main (SoTimeout.java:17)

Seeing that tryport of SoTimeout went to 65535, ServerSocket(tryport)
must have thrown IOException.

My FreeBSD machine is set up so that it uses IPv6, and I am afraid this
failure is because libraries/clib/net/PlainSocketImpl.c does not fully
support IPv6 addresses.  For example, gnu_java_net_PlainSocketImpl_socketCreate
always calls KSOCKET(AF_INET, type, 0, &fd).
