- -- 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
