I am not 100% sure, if that answer the question, but the C++ standard requires
a conforming implementation to provide following declarations, even if the
sizeof(double) == sizeof(long double).
constexpr long double acosl(long double x);
constexpr long double asinl(long double x);
And because double and long double are required to be distinct types, even if
they size are the same and use same representation.
