Bug description:  php (CLI) exec function passes no stderr output

Description:
------------
PHP CLI version 5.1.8 thru 5.2.1 Windows Binary - exec() function, when
error is generated passes STDERR no problem to CLI window.  5.2.2+ STDERR
output has vanished.  Nothing in documentation or search suggests what
happened.  No other changes 5.2.1 just downloaded and tested with generic
setup (no php.ini or other modifications) stderr from exec() functions
perfectly.  5.2.2+ system() apparently passes stderr properly, but is not
useful for most of what we do. STDOUT appears to be fine all versions.

Oddly, 5.2.2+ versions still work correctly with cygwin/bash 3.1

Note in 5.2.2 changelog contains this bit:
- Fixed commandline handling for CLI and CGI. (Marcus, Johannes)


Thanks,

Chip Keefer

Reproduce code:
---------------
<?php
$result = exec('cd c:\non_existant; dir nonexistant');
echo "$result\n";
?> 


Expected result:
----------------
NJPC3916:php5.22$ php test_exec.php 
php test_exec.php 
The system cannot find the path specified.

- Works properly with cygwin

Actual result:
--------------
C:\php5.22> php test_exec.php


C:\php5.22> 

No STDERR
