Cygwin tries to emulate linux/POSIX. CreateNamedPipe is not a linux/POSIX function. Cygwin does not implement Windows functions. So, no, Cygwin does not implement its own versions of CreateNamedPipe or ReadFile. As I suggested, if you want to build a pure Windows program, you shouldn't be using Cygwin.
