[issue17797] Visual C++ 11.0 reports fileno(stdin) == 0 for non-console program

[Jean-Charles Lefebvre]

Hi all, a small update to confirm this issue with version 3.5.0a2 embedded in a native C++ GUI application, having everything built with VS2013 SP4.

Same execution flow as described by Mateusz in msg198689.

I've modified Python/pylifecycle.c file according to Tomasz's attached patch.
It just "works for me" and I've just slightly modified the #ifdef line:

#if defined(MS_WINDOWS) && defined(HAVE_FSTAT) && defined(_MSC_VER) && _MSC_VER >= 1700 && _MSC_VER < 2000

It would definitely be nice to have this workaround applied to the 3.5 branch since MS' fix is lost in release cycle. Would it be too intrusive?
