2023-11-20stdio: Fix bugs in commit 3d94e07c49b5Takashi Yano1-0/+2
The commit 3d94e07c49b5 has a few bugs which cause testsuite failure in libstdc++. This is due to excess orientation check in __srefill_r() and _ungetc_r(). Further, sscanf() family also calls ssvfscanf() family with fp->_file == -1. This causes undesired orientation set/check for sscanf() family. This patch fixes these problems. Also, as in GLibC, do not set orientation in ungetc, and only set, but do not check orientation in ungetwc. Fixes: 3d94e07c49b5 ("newlib: libc: Fix crash on fprintf to a wide-oriented stream.")
