Missing files when using Zip Encoding Library

[eluser]captainredmuff[/eluser]
Ok, so i spent a few hours yesterday sifting through the Zip Encoding Library to see if i can find a fix for this issue. I haven't been able to fix this issue so any help would be greatly appreciated as this is holding up development of one of our current projects.

Whilst i admit i don't entirely understand the two methods, _add_dir() and _add_data(), i have noticed that the method _add_data() uses gzcompress() to "compress" the data being passed to it a la;

Code:

//line #160
$gzdata = gzcompress($data);

Upon reading the documentation for this function, php.net - gzcompress(), it appears that no compression is being applied due to the missing (optional) second parameter which should be specified as an integer between 0 - 9 to define the level of compression desired. Seeing that this parameter is missing and along with the documentation for the function, i can only assume that no compression is being applied.
