Re: cygwin-64 2.3.1. bash fails when running under FSF emacs 24.5

Before upgrading another machine (still on win7/64), I updated cygwin64 on
it and pulled fsfemacs 24.5 (the existing binary on gnu's site) on it...

Did the same test there and on win7 it works. Could this be a Windows 10
related issue?

D.
PS: I'll stop cc'ing the emacs list after this message as I also think it
is more likely a cygwin issue.
