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. */
