| /* 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. */ |
