Yes. While new development may choose f9x, there's still a lot of legacy
f77 code which requires the fixed format, unfortunately.

The compiler setting is another thing, though. By now, gfortran should
be able to compile f77 code as well. (If not, file a bug; to gfortran,
of course  :-) to make it better.) Anyway, a user can always change the
setting to use whatever he/she needs.
