Actually, this is a very bad practice from the point of view of
portability. The kind numbers are not guaranteed to have specific
values. Fortunately, Fortran-90 provides a portable way of
specifying non-default kinds (through the SELECTED_REAL_KIND
and SELECTED_INTEGER_KIND intrinsics). Why not use those, and
make the code portable?
