the header is included for all but android, and the implementation is present
for all platforms. why make this win-only here? i think that this should at
least be harmonized with inclusion of the header above.

Yes, it should be harmonized. I'm going to mark this as OS_WIN only for now,
since I don't yet care about the non-win implementations and that slightly
minimizes runtime work elsewhere.
