ok, I am having issues with the following code STDERR seems to be ending up in the STDOUT handle on the open3

#!/usr/bin/perl
use strict;
use warnings;
use IPC::Open3;

chdir "C:\\";

my ( $writer, $reader, $err, $pid );

my $SVN_LIST = "svn status --depth infinity --no-ignore C:\\Nonexistan
+t_DIR";

$pid = open3( $writer, $reader, $err, $SVN_LIST );
waitpid $pid, 0;

while (<$err>) { # causes "Use of uninitialized value $err in <HANDLE>
+"
    print "$_";  # and    "readline() on unopened filehandle"
}

while (<$reader>) {
    print "$_"; # Prints the error message
}


$SVN_LIST = `svn status --depth infinity --no-ignore C:\\Nonexistant_D
+IR`;
#error message comes out on STDERR since it isn't captured.
print "$SVN_LIST"; # prints nothing.

when I run this the SVN command in a cmd shell it will return via STDERR "svn: warning: 'C:\Nonexistant_DIR' is not a working copy". I have proved it to myself by running the following on a command prompt

svn status --depth infinity --no-ignore C:\NON_EXISTANT_DIR > xxx 2> e
+rr

With this the file xxx is empty and the file err has the data in it.

What am I missing on the open3 that I am not getting STDERR output in what from my reading should be in the $err I pass.

Or is the issue I am having related to the fact I am running on a Windows platform

I am using activestate perl version v5.16.3 built for MSWin32-x86-multi-thread.
