+
+This patch was added for 64bit host machines. In the compile process python
+is checking if platform is a 64bit platform using sys.maxint which is the host's
+value. The patch fixes this issue so that python would check if TARGET machine
+is 64bit not the HOST machine. In this way will have "dl" and "imageop" modules
+built if HOST machine is 64bit but the target machine is 32bit.
