#define _GLIBCXX_LONG_DOUBLE_ALT128_COMPAT
#include <charconv>
int main()

It seems there are a few __extension__ where they should not be:
inline to_chars_result
to_chars(char* __first, char* __last, _Float128 __value) noexcept
{
__extension__
return to_chars(__first, __last, static_cast<__float128>(__value));
}
