windows: msvc: Define STDIN/OUT/ERR_FILENO.
This commit (c290e79cf0
) was originally back-patched to v15. Commit97550c0711
added a new use of STDERR_FILENO, and it was back-patched all the way to v11, thus breaking MSVC builds for v11 through v14. Since STDERR_FILENO is now needed on older versions, let's back-patchc290e79cf0
down to v11, too. Here follows the original commit message describing the change: Because they are not available we've used _fileno(stdin) in some places, but that doesn't reliably work, because stdin might be closed. This is the prerequisite of the subsequent commit, fixing a failure introduced in76e38b37a5
