Hi Keith.

Never having used gcj before I thought I would try your program for the hell
of it:

$ ./a.exe
>startServer
Trying to bind port 5001
Listening on port 5001
>Accepted connection from : localhost/127.0.0.1

It's different in that I got "localhost/127.0.0.1" rather than
"127.0.0.1/127.0.0.1" but I assume that's OK.

I'm on an XP system connected to a LAN using the same gcj package as
yourself.

Cheers

Mike Thomas.

I have gcj-3.2-20021210-1 on my system.  The following program does not
work correctly with mingw gcj.  However, it does work gcj on linux and
the IBM JDK 1.3.1 on Windows.

Run the program below and then type "startServer".  After that open a
DOS window and type "telnet localhost 5001".  In the window where you
typed "startServer" you should see "Accepted connection from :
127.0.0.1/127.0.0.1" ... however, this does not happen with the mingw
gcj.  I compiled the program with the following command :

         gcj --main=Server Server.java

Thanks,
