I think the new convention (per some post on chromium-dev) is to put all of the
#if defined(OS_FOO) ... #endif blocks after the other #includes. Feel free to
move the OS_POSIX block too.

I can't find the email now, but the recollection of people I polled here is that
the consensus for this kind of thing was a single block at the end for platform
includes, which is internally ordered alphabetically.
