gfortran 4.5 has:
                struct force_type D.1375;
                force_type.0.xext = 0.0;
                [...]
                D.1375 = force_type.0;
                (*(struct force_type[0:] * restrict)
force.data)[(integer(kind=8)) i + force.offset] = D.1375;

gfortran 4.4 has:
                force_type.0.xext = 0.0;
                [...]
                (*(struct force_type[0:] *) force.data)[(integer(kind=8)) i *
force.dim[0].stride + force.offset] = force_type.0;

Thus the "restrict" (plus the additional assignment) makes the difference at
front-end level.
