Re-reading this I think there was some confusion, definitely so on my part.
tcp_keepalives_interval relies on TCP_KEEPINTVL, with the Windows equivalent
being SIO_KEEPALIVE_VALS. TCP_KEEPCNT is for tcp_keepalives_count which indeed
is not supported on Windows. Jonathans original question was regarding _count
and _timeout and not _interval.
I do agree that all of these notes may just as well be added to the text, the
option client_connection_check_interval following these have text about
platform compatibility without using a note.
