1.3.14-1: poll and accept bug/incorrect behavior

[Tigran Mkrtchyan <tigran at mail dot desy dot de>]

Hi All,

I am porting application from Unix to Cygwin. The application works fine
on SunOS, IRIX, Linux and native win32. But it's failed to work under
cygwin. The problem is poll implementation. In our the code we have a
part, which calling the poll before accept as it have to check for several
sockets at the same time.

As I can see in the winsup/cygwin/poll.cc:94-97

 if (!sock)
      fds[i].revents |= POLLIN;
 else
       switch (sock->recvfrom (peek, sizeof (peek), MSG_PEEK,  NULL, NULL))

in case of a socket, poll only checks for reading, but not for incoming
connection, while peek_socket from winsup/cygwin/select.cc:1150 does it
correctly.

I hope it's correct mailing list.

	Tigran.
