Description:
------------
chdir('D:/') doesn't work. It may have (sorry - I've only just noticed the error log as the script runs unattended).

A proof has been supplied.

Using PHP 5.2.2RC2-dev (cli) (built: Apr 12 2007 04:03:00)

Reproduce code:
---------------
<?php
echo 'Current Directory is ', getcwd(), PHP_EOL;
echo 'Path to script is ', dirname($argv[0]), PHP_EOL;
echo 'Change to path of script : ', (chdir(dirname($argv[0])) ? 'Success' : 'Failed'), PHP_EOL;
echo 'Current Directory is ', getcwd(), PHP_EOL;
echo 'Root to path to script is ', dirname(dirname($argv[0])), PHP_EOL;
echo 'Change to root of path of script : ', (chdir(dirname(dirname($argv[0]))) ? 'Success' : 'Failed'), PHP_EOL;
echo 'Current Directory is ', getcwd(), PHP_EOL;
?>

Expected result:
----------------
Current Directory is C:\
Path to script is D:\PHP Quickies
Change to path of script : Success
Current Directory is D:\PHP Quickies
Root to path to script is D:\
Change to root of path of script : Success
Current Directory is D:\


Actual result:
--------------
Current Directory is C:\
Path to script is D:\PHP Quickies
Change to path of script : Success
Current Directory is D:\PHP Quickies
Root to path to script is D:\
Change to root of path of script :
Warning: chdir(): No such file or directory (errno 2) in D:\PHP Quickies\chdir_test.php on line 7
