+Subject: [PATCH] Detect clang
+
+Check for clang compiler since we need to disable
+unused-function warning for clang, at same time
+pass werror when checking for compiler options if
+werror is enabled so spurious options do not get
+enabled. Only the ones that are supported by given
+compiler are accepted.
