The wstring and wstring_view typedefs should be enabled even if <wchar.h> isn't supported, because char_traits<wchar_t> works unconditionally. Similarly, the std::hash specializations for wide strings do not depend on <wchar.h> support. Although the primary template works OK for std::char_traits<wchar_t> in the absence of <wchar.h> support, this patch still defines it as an explicit specialization for compatibility with declarations that expect it to be specialized. The explicit specialization just uses the same __gnu_cxx::char_traits base class as the primary template. libstdc++-v3/ChangeLog: PR libstdc++/98725 * include/bits/char_traits.h (char_traits<wchar_t>): Define explicit specialization unconditionally. * include/bits/basic_string.h (hash<wstring>): Define unconditionally. Do not check _GLIBCXX_USE_WCHAR_T. * include/bits/stringfwd.h (wstring): Likewise. * include/debug/string (wstring): Likewise. * include/experimental/string_view (experimental::wstring_view) (hash<experimental::wstring_view>): Likewise. * include/std/string (pmr::wstring, hash<pmr::wstring>): Likewise. * include/std/string_view (wstring_view, hash<wstring_view>): Likewise. |
