Description:
------------
Use the zipped distribution of PHP 5.1.2 for Wimdows, I have been able to get the core PHP active, but can not get the PDF functions to work.  If I enable the extensions PHP_PDF.DLL or PHP_CPDF.dll, I receive an error saying these versions were compiled with a different version, and PHP aborts.  I tried installing the PDFLIB Lite package, but the compiled DLL is not recognized as a valid PHP DLL when added to the list of extensions.

Is there newer version of these files, or perhaps an alternate installation?  

Actual result:
