The cygwin header has been recently update and reshuffled.

The definition is in /usr/include/sys/time.h

If I define _GNU_SOURCE or _XOPEN_SOURCE=700 the project build successful, but it's not work, because boost::asio::ip::tcp::socket raise exception that socket.available() is not supported(but it was).

try using __XSI_VISIBLE=4
