Masayuki Yamamoto added the comment: I agree to use setmode() at _pyio module for Cygwin. However, I have two reasons that I disagree to the implementation of os.setmode(). First, FreeBSD has another setmode() that operate file permission bits [1]. Therefore the implementation of os.setmode() will be confused to those users. Second, msvcrt.setmode() isn't used almost in standard library, the function is just used by _pyio module and subprocess test. Thus I think there aren't much need that implements setmode() to os module.
Easy way for a solution of import error on Cygwin, setmode() is implemented on _pyio using ctypes. then Cygwin CPython forget setmode(). Otherwise it's hard way, For avoiding confliction to other platforms, I'd propose to create the cygwin module. I thought a solution implementing imitation msvcrt module, but it is unreasonable because Cygwin doesn't have other Windows API. I tried written the patch of easy way that implements setmode() into _pyio. This patch is included parts to succeed import _pyio.
