Thank you, Corinna.

I have tried your patch. It nicely works for me, too.
And your workaround is definitely better than mine.

One small thing to be improved is here:

+      if (echo_cnt > 0
+	  && ReadFile (echo_r, outbuf, MIN (rlen, echo_cnt), &n, NULL))

echo_cnt returned by ::bytes_available() is actually
not a number of bytes available in the pipe. This is
because ::bytes_available() returns "nleft" instead
of "navail" when "nleft" is non-zero.

Therefore, "rlen" should be used here rather than
"MIN (rlen, echo_cnt)".

By the way, should we go to cygwin-developer mailing list?
