Cygwin 3.1.x fails if I have the use legacy console box checked in Windows 10

Tue Nov 5 03:34:00 GMT 2019

I'm using Win 10 1903 build 18362.449 and if I check the use legacy 
console box under properties options in the console then I get the 
following error with ssh built with cygwin.
       0 [main] ssh 1942 C:\Program Files\OpenSSH\bin\ssh.exe: *** 
fatal error - couldn't initialize fd 0 for /dev/cons0

If I use 3.07 this works.  Also if I use the March 27 2019 snapshot 
it works, but if I use the March 31 2019 or later snapshot I get the 
above error.  I couldn't find anything that said that Cygwin now 
didn't support the legacy console thus I'm reporting this issue.
