From 1bc7c0daece11b36abebc48b9113193056289fe6 Mon Sep 17 00:00:00 2001
From: Thuy Tran <thuy.tran.xh@renesas.com>

Subject: [PATCH] Silenced -Wcast-function-type, -Wsizeof-pointer-div and
-Wstringop-truncation options of GCC 8.1
Current GFX source code will get compilation error with GCC 8.1,
because it is defined in makefile to use -Wall to enable all Warnings
check.
-Wcast-function-type, -Wsizeof-pointer-div and -Wstringop-truncation
are new Warnings from GCC 8.
