This is a problem caused by this change:
http://cygwin.com/ml/cygwin/2004-10/msg00364.html
And, then, the problem was noted here:
http://cygwin.com/ml/cygwin/2004-10/msg00904.html
The problem is that cygwin is now behaving like linux in that timed
reads from a pty/tty work correctly. It is not behaving like linux in
that once you get an EOF on a read using stdio, you get EOF forever
after.
I've made a cygwin-specific correction to the newlib library to make
cygwin work more like linux. I will generate a cygwin snapshot sometime
soon which should have a fix for this problem. Keep an ey on:
