+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
+
+Signed-off-by: Khem Raj <raj.khem@gmail.com>
+
+1. Keep '-std=c++11' and '-std=gnu99' to fix native build error
+with old gcc (such as gcc 5.4.0 on ubuntu 16.04), for clang
+we will remove them through GRPC_PYTHON_CFLAGS at do_compile
+in bb recipe.
+
+2. While export CC="gcc ", cc_args is None, it will
+cause subprocess.Popen always return 1. On centos 8, if you don't
+install package libatomic, there will be a native build error
+`cannot find /usr/lib64/libatomic.so.1.2.0'.
+
+Add no harm '-g' to cc_args if cc_args is empty.
+
+Upstream-Status: Inappropriate [oe specific]
