/* What are the C types corresponding to the real(kind=10) and

   real(kind=16) types? We currently rely on the following assumptions:

     -- if real(kind=10) exists, i.e. if HAVE_GFC_REAL_10 is defined,

        then it is necessarily the "long double" type

     -- if real(kind=16) exists, then:

         * if HAVE_GFC_REAL_10, real(kind=16) is "__float128"

         * otherwise, real(kind=16) is "long double"

   To allow to change this in the future, we create the

   GFC_REAL_16_IS_FLOAT128 macro that is used throughout libgfortran.  */
