select() not interrupted by signals

- Subject: select() not interrupted by signals
I had previously reported "select() hanging after terminal killed"
(http://cygwin.com/ml/cygwin/2011-05/msg00418.html).
It turns out that select() does not get interrupted by a SIGWINCH signal
either (with likely the same cause).
This raises problems with interactive programs that want to react to
window size changes (like text editors).
See attached updated test case; run the program, while select() is
waiting (before 5 second timeout each), change window size and see no
interrupt.
On other systems, select() is interrupted (test case: from mintty,
remote login to SunOS; also showing the terminal is not involved in the
problem).
This bug did not exist in cygwin 1.5; I see some Changelog entries from
2011-12-13 or 2012-01-22 which might be related.
