?? is this intended?
base/logging.h is included virtually everywhere, this might affect build time.
Why is this needed?

See earlier discussion:
https://codereview.chromium.org/2518253002/diff/80001/base/logging.h#newcode24 +
palmer's off-comment reply: https://codereview.chromium.org/2518253002#msg37

I hadn't thought of the build cost side-effect though but looks like windows.h
is already included in 79 headers in base/ including time.h so it's likely
spread into virtually every .o already:

+#include <windows.h>

nit: just realized while doing the above search that windows.h is included in
logging.cc, that should be removed now that the include is in its .h

Done.
