 // On MSVC, including StaticConstructors.h causes all global objects not to be
 // automatically initialized by the C runtime. This is useful in some specific
 // cases (e.g., the *Names.cpp files), but can be dangerous in others. We don't
 // want StaticConstructors.h to "pollute" all the source files we #include here
 // accidentally, so we'll throw an error whenever any file includes it.
