> libstdc++: Fix build failure due to missing <langinfo.h> [PR98374]
>
> This should fix a build failure on Windows which lacks <langinfo.h>,
> from which we use nl_langinfo() to obtain the radix character of the
> current locale. (We can't use the more portable localeconv() from
> <clocale> to obtain the radix character of the current locale here
> because it's not thread-safe, unfortunately.)
>
> This change means that on Windows and other such platforms, we'll just
> always assume the radix character used by printf is '.' when formatting
> a long double through it.
