   If long double is ABI-compatible with double, it should define
   __NO_LONG_DOUBLE_MATH to 1; otherwise, it should leave
   __NO_LONG_DOUBLE_MATH undefined.
   If this build of the GNU C Library supports both long double
   ABI-compatible with double and some other long double format not
   ABI-compatible with double, it should define
   __LONG_DOUBLE_MATH_OPTIONAL to 1; otherwise, it should leave
   __LONG_DOUBLE_MATH_OPTIONAL undefined.
   If __NO_LONG_DOUBLE_MATH is already defined, this header must not
   define anything; this is needed to work with the definition of
   __NO_LONG_DOUBLE_MATH in nldbl-compat.h.  */
