What if the .exe has another name?

The purpose of your function looks similar to what Mihail Konev
did for the MinGW-w64 project:
  
https://mingw-w64-public.narkive.com/s7kYRrtG/patch-mingw-w64-add-include-iscygtty-c

Instead he looked for pipes matching:
"\Device\NamedPipe\(cygwin|msys)-[a-fA-F0-9]{16}-pty[0-9]{1,4}-(from-master|to-master|to-master-cyg)"

BTW.
I created my own version of in his work in my Envtool
program. The 'is_cygwin_tty()' function:
