Awesome. Thanks for doing this work. I believe the Cygwin developers had concerns about this change inadvertently breaking some applications.

For example, when running cmd.exe through fdev and invoking > isatty.exe from there, it's all zeroes from isatty() again. Unfortunately, cmd.exe does not appear to use the C runtime IO library, and it doesn't pass on inherited file descriptors --- except for the standard handles via CreateProcess. It's a shame, too, because cmd understands the syntax for manipulating the first ten file descriptors in much the same way that a unix shell does. I think it would work for other families of process though, and it's still an improvement.
