    Diffs (or patches, these are synonyms) are applied with a program
    called "patch".  The text above is only a fragment of a complete
    diff, and patch won't process it. Your best bet is to "apply" it by
    hand: replace the lines marked with "-" with those beginning with
    "+". The block displayed above begins on line 74 in
    asio/detail/win_iocp_io_service.hpp.
