If you're #including <mutex>, haven't you locked yourself into C++11 (or
better) anyway? In that case, you should use curly braces for your
initializer (or at least stop saying `using namespace std;`).
For existing code where `mutex` is a global variable, you'll be fine. If
using namespace std;
to existing code, you'll get a compiler error because the name `mutex`
is now ambiguous.
If you wanted to warn about this in *all* cases, you'd need an
additional warning to detect function declarations in local scope, since
that's what C++ would treat this as. Clang doesn't have such a warning,
but perhaps you could convince someone to add it.
