From 28cfdbbcb96a69087c3d21faf69b5eae7bcf6d69 Mon Sep 17 00:00:00 2001 From: Hodorgasm <nsane457@gmail.com> Date: Wed, 11 May 2016 21:42:07 -0400 Subject: [PATCH] Cast to unsigned while left bit-shifting GCC-6 now treats the left bitwise-shift of a negative integer as nonconformant so explicitly cast to an unsigned int while bit-shifting.
