+Subject: [PATCH] Allow GCC 4.9 to compile Chromium
+
+In order to implicit cast an lvalue to an rvalue when returning
+from a function, the return type and type of variable in the return
+statement previously had to be exactly the same. When this was not
+the case, std::move was required. For instance, when returning a
+std::unique_ptr<Derived> variable in a function with a
+std::unique_ptr<Base> return type, std::move is required.
+
+DR 1579 changed this, and allows for implicitly converting
+to the return type, if the return type has a constructor(T&&), where
+T is the type of the local variable being returned. DR 1579 was
+implemented in GCC 5, but not in GCC 4.9 and below. By explicitly
+qualifying the local variable with std::move, we allow for compiling
+with GCC 4.9 and incur no performance penalty. The code is still
+absolutely correct to the word of C++11.
