I contacted with Enrico who tells me the patch that I have shown.

His reply is the below.

**********************************
Dear Tatsuro,

unfortunately I do not have an STC other than the evidence that the
above patch works for gnuplot. I have always had problems with O_NONBLOCK
on cygwin. For example, see
https://www.mail-archive.com/cygwin@cygwin.com/msg104221.html

**********************************
At this moment, the above is that I can do for this matter.

Tatsuro
