The way the binary record length is encoded appears to be changed
from g77 to gfortran.
1. Compatibility between gcc-3.x.x - g77 and gcc-4.0 - gfortran
-- not compatible and not a big problem, but don't know why it
should change
2. Compatibility between gcc-3.x.x - cpp and g77 -- compatible.
3. Compatibility between gcc-4.0 - cpp and gfortran -- the problem

Try looking at: <http://gcc.gnu.org/wiki/GfortranUnformattedSequentialIo>.
The record size is 64bit on all targets now unlike in g77 so it is binary compatiable to g77 on 64bit
targets.

Subject: Re: gfortran binary file format
Thanks for pointing me to the background. I searched, but used the wrong
words.
I also recall something about 32 bit initial implementation for gfortran
in gcc-4.0, and
a record size of 64bit for all targets is counter to that idea.
What about compatability between gcc-4.0 - c++ and gfortran ? Are not
c++ targets 32 bit?
