From 984c25b74da085c6ae6b44a87bbd5f8afc9be331 Mon Sep 17 00:00:00 2001
From: Rich Felker <dalias@aerifal.cx>
Date: Wed, 2 Jul 2014 12:09:48 -0400
Subject: [PATCH] fix failure of wide printf/scanf functions to set wide
orientation
in some cases, these functions internally call a byte-based input or
output function before calling getwc/putwc, so they cannot rely on the
latter to set the orientation.
