From 92f478657c5544eba560047c39eba8a030ddb83e Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Mon, 18 Jul 2022 17:06:34 -0700 Subject: [PATCH] windows: msvc: Define STDIN/OUT/ERR_FILENO. 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 in 76e38b37a5.
