26/* What are the C types corresponding to the real(kind=10) and
27   real(kind=16) types? We currently rely on the following assumptions:
28     -- if real(kind=10) exists, i.e. if HAVE_GFC_REAL_10 is defined,
29        then it is necessarily the "long double" type
30     -- if real(kind=16) exists, then:
31         * if HAVE_GFC_REAL_10, real(kind=16) is "__float128"
32	 * otherwise, real(kind=16) is "long double"
33   To allow to change this in the future, we create the
34   GFC_REAL_16_IS_FLOAT128 macro that is used throughout libgfortran.  */
