From ca7fc7e962fa067ba31f76a6e5828537394f6481 Mon Sep 17 00:00:00 2001 From: Dan Streetman Date: Mon, 11 May 2015 18:53:36 -0400 Subject: [PATCH] lib: correct 842 decompress for 32 bit Avoid 64 bit mod operation, which won't work on 32 bit systems. Simple subtraction can be used instead in this case.
