Dimitry Andric e8b1dca337 science/dlib-cpp: fix build with clang and libc++ 19 ... As noted in the libc++ 19 release notes [1], std::char_traits<> is now only provided for char, char8_t, char16_t, char32_t and wchar_t, and any instantiation for other types will fail. This causes science/dlib-cpp to fail to compile with clang 19 and libc++ 19, resulting in errors similar to: /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned int>' 820 | static_assert(is_same<_CharT, typename traits_type::char_type>::value, | ^ /wrkdirs/usr/ports/science/dlib-cpp/work/dlib-19.24/dlib/bigint/../unicode/unicode.h:496:26: note: in instantiation of template class 'std::basic_string<unsigned int>' requested here 496 | inline const ustring convert_utf8_to_utf32 ( | ^ /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here 23 | struct _LIBCPP_TEMPLATE_VIS char_traits; | ^ These can be fixed by using `char32_t` instead of `uint32_t` for the `unichar` type. Also, clang 19 now implements CWG 96 [1], which requires a template argument list after a 'template' keyword, resulting in errors similar to: /wrkdirs/usr/ports/science/dlib-cpp/work/dlib-19.24/dlib/filtering/../global_optimization/find_max_global.h:61:130: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw] 61 | static auto go(T&& f, const matrix<double,0,1>& a) -> decltype(call_function_and_expand_args<max_unpack-1>::template go(std::forward<T>(f),a)) | ^ This can be fixed by adding `<>` after the `go` identifier.
