Comment:
So the question would be if we an detect at configure time what a "long double" looks like and then make fortran use the same type for CCTK_REAL16 (no matter whether this is 10, 12 or 16 bytes). I don't think we need to make sure that a CCTK_REAL16 actually occupies 16 bytes, just that it is "better" than CCTK_REAL8 and is the same in both C/C++ and Fortran code.
