Hello,
I updated my cygwin yesterday, because I found strange bug when using boost::asio::ip::tcp::socket for sending some text information(some information became broken). I haven't got such bug under my Linux OS, so I decide upgrade the cygwin.
After successful updating of cygwin I can't build my project.

The first error of compiler is:

In file included from /usr/include/boost/thread/thread_time.hpp:10:0,

gettimeofday(&tv, 0); //gettimeofday does not support TZ adjust on Linux.

The second error message:
/usr/include/boost/date_time/microsec_time_clock.hpp:84:26: note: (if you use '-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated)

sigfillset(&new_mask);

I have tried to use -fpermissive, but it's not help me. I also have tried to add define _GNU_SOURCE, _POSIX_C_SOURCE=200809L, _XOPEN_SOURCE=700. 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).
I also try full reinstall of cygwin, but it's not help. I attached output of command "cygcheck -s -v -r". 

What it may be the problem and how I may resolve it?
