+Additional changes: gzopen64() - 20090930
+------------------------------
+An additional change has been applied to check on the zlib extension by probing
+gzopen64() as well as gzopen() in the PclZip() function. This is due to a
+recent change in the Zlib library, whereby the gzopen() function has been
+updated and moved to gzopen64().
+This problem has been reported to PhpConcept (editors of PclZip).
