+From b02be74a2eff8abc612ef84f30e0fbce6a7f65f5 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] setup.py: Do not mix C and C++ compiler options
+
+EXTRA_ENV_COMPILE_ARGS is used both with CC and CXX
+so using -std=c++11 or -std=gnu99 together will cause
+build time errors espcially with clang
+
+error: invalid argument '-std=gnu99' not allowed with 'C++'
+
+gcc7 ( defaults are -std=gnu11 and -std=gnu++14 )
+ as well clang default to these standards mode or newer
+anyway
