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


It looks like the changes between 3/27 and 3/31 were to support 24-bit color in the normal console in 1703 or later and to fake the support for legacy console. I can't currently compile anything, but I'm guessing that something went wrong with that change for legacy console. The other changes seem less likely to cause the problem based on reading the diff.

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.
