--- Comment #5 from Angus Gibson <angus at agibson dot me> ---
I agree that it's not ideal... Unfortunately an awkward file format, and
fortran is usually the wrong language for this kind of IO anyway. I guess the
note that "A processor may prohibit some control characters from appearing in a
formatted stream file" is a bit of an escape clause for gfortran here.

I would argue that because the position is obtained from an inquire statement,
we should be able to re-set the file position to that (indeed, Intel Fortran,
not that it defines the standard, does what I expect). Anyway, I'm happy for
this to go either way.
