At least one Fortran compiler I have used generated faster code with these
declarations than with the alternative a(n), b(n).  The latter did some
initialization, even when it wasn't used.

I would recommend that you regard a dimension of 1 for an argument as
meaning that the dimension is undefined.  It's not pretty, but it works.
