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
