================
Comment at: lib/Sema/SemaDecl.cpp:2157
   if (getDiagnostics().getSuppressSystemWarnings() &&
-      (Context.getSourceManager().isInSystemHeader(Old->getLocation()) ||
+      // Some standard types are defined implicitly in Clang (e.g. OpenCL).
+      (Old->isImplicit() || New->isImplicit() ||
----------------
Is it necessary to check whether New is implicit? I was just wondering when or how an implicit definition would redefine a typedef.
