Subject: fix failure of wide printf/scanf functions to set wide orientation
X-Git-Tag: v1.0.4~21
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7bbf7c12548fef40a0872e32d5c6f0903c5ea147;p=oweals%2Fmusl.git

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.
