Yeah I did actually, I had to mess with the
gcj sources a little bit.  Here's what I did, I
think the last of these fixes your problem.  Sorry
not in diff format, I've lost the originals
momentarily. Sorry, not 20030313 but 20030331
snapshot.


FILE:
libjava/gnu/java/nio/natSocketChannelImpl.cc

jint 
gnu::java::nio::SocketChannelImpl::SocketRead (jint
fd, jbyteArray data,jint offset, jint length)
{
   //MLM: hack, cast data to a char*
  int result = ::recv (fd, (char *)data, offset,
length);
  //int result = ::recv (fd, data, offset, length);

...

jint
gnu::java::nio::SocketChannelImpl::SocketWrite (jint
fd, jbyteArray data,jint offset, jint length)
{
   //MLM: hack, another cast
  int result = ::send (fd, (char *)data, offset,
length);
  //int result = ::send (fd, data, offset, length);

FILE:
libjava/java/net/natPlainDatagramSocketImpl.cc

add this to the top somewhere:
   #define ECONNREFUSED WSAECONNREFUSED

FILE:
libjava/gnu/java/nio/natSelectorImpl.cc

In this file, I actually had to copy _Jv_select out
of libjava/include/posix.h and paste it statically
in.  Yuck, but whatever, it gets the job done and I
didn't want to fool around with the linking.
