It's a bug in cygwin. Hopefully, it will be fixed soon (i have a
working patch but it needs some cleanup).

Meanwhile, as a workaround, you may want to use select() before read()
and doesn't rely on termios features like this. Using select() is a
cleaner solution because it would work on any type of input, not just
ttys.
