I'm Wearing a Uniform!

I'm looking to write a script that might use PCNTL functions: http://www.php.net/manual/en/book.pcntl.php I'm just wondering before I spend the time to compile PHP with --enable-pcntl. If you guys have any ideas if PCNTL will even work with Uniform Server since PCNTL supposedly only works on UNIX systems: http://www.php.net/manual/en/pcntl.installation.php
