Bud Davis is back and working on the pluggable record markers patch. Expect it
to be completed and committed within a few weeks.
There is no simple solution that is right for all situations. Gfortran uses
64-bit record markers by default since we want compatibility between LP32 and
LP64 bit platforms (which incidentally g77 doesn't provide), and we want to
support records bigger than 2 GB.
There has been some discussion about a byteswapio patch, but nothing has been
done. Patches are welcome, of course.
And, I would hardly classify the bug as "critical".
If you want portable binary io you're probably better off using a library such
as netcdf anyway.
