No dbg dll available for versions in XAMPP 1.5.4a

[tnine]

Hi all,
I've used XAMPP for quite some time, and I recently downloaded version 1.5.4a. I'm still using php 4, so I ran the switch.bat and my version is 4.4.4. Unfortunately no php_dbg.dll exists for that version, the highest available is for version 4.4.2. Is it possible to get the dll for the latest version?

Thanks,
Todd
