I'm not convinced this is a good idea. We're essentially adding a bunch of conditionals where we should really just implement the `long double` overload. Also, IMO we should just provide the symbol for `long double` on every platform and not just on ones where `long double` and `double` have different representations. It's not like we're saving much by providing it only sometimes.
