Adib: Trying to build against March 13 libs. Patched with no errors, but I get this message halfway through build;

Sorry, but not being a programmer I can't really help debugging here, but lots of the complaints relate to the gint variable, which is what is on the first line complained about in script.cpp - "while (bytes < sizeof(gint)*2)"

I've attached my patch version of the script.cpp file if you want to check it.
