I think this should be removed. Unless the types are used in the header file
itself, the header can be included in .cc files.

Just to double check: given that HANDLE and OS_POSIX are used in this file I
would have thought the include belongs in this file.

I don't believe that we have any platforms where OS_WIN and OS_POSIX are both
true, so the previous #elif was correct.
