We don't need to have <wchar.h> support in order to delete overloads for inserting wide characters into narrow streams. libstdc++-v3/ChangeLog: PR libstdc++/98725 * include/std/ostream (operator<<(basic_ostream<char, Tr>&, wchar_t)) (operator<<(basic_ostream<char, Tr>&, const wchar_t*)): Always define as deleted. Do not check _GLIBCXX_USE_WCHAR_T.
