Thanks!  Windows Subsystem for Linux, right?  We know about that. 
Microsoft's Linux kernel emulation is missing that socket option.  My
position has been that Microsoft is responsible for a complete
emulation, and WSL is still in beta.  I may yet relax that position and
apply a more sophisticated version of this workaround; there've been a
number of people hitting this.  See
<https://github.com/mobile-shell/mosh/issues/781> for a little more
discussion and various links.  If this *isn't* WSL, then please tell us
where the problem *is* cropping up.

Also, we generally ask that contributors use GitHub to submit code; that
avoids patch hassles, runs submissions through CI and exposes it to
review better.  (In this case it doesn't matter much, I've got this
one-liner already sitting in my repo.)
