fmt/std.h:143: multiple definition of `fmt::v12::detail::normalize_libcxx_inline_namespaces(fmt::v12::basic_string_view<char>, char*)';

Since the last commit, we got this error many time during link in our project:

fmt/std.h:143: multiple definition of 'fmt::v12::detail::normalize_libcxx_inline_namespaces(fmt::v12::basic_string_view<char>, char*)';

Everything was working before. This error seems directly related to the latest fmt commit.

Thanks for reporting. Looks like #4560 accidentally made this function non-inline despite it being defined in a header.
