It is used by default, providing CPU and OS support it, and mdrun is able
to detect that they support it. You'll find messages in the logfile to
that effect. Fortran, as far as I understand, is by default not used on
Linux, since it provides not much improvement over C (and certainly none
over assembly ;-).
