I am trying to read the binary files produced with amd64 on a 32 bit machine.
This is not possible because the record header changed from 4-bytes to 8-bytes.
Can this be fixed? Example program:

         write(1)'Z'
         end

produces fort.1 on opteron with the following content if opened in emacs:
^A^@^@^@^@^@^@^@Z^A^@^@^@^@^@^@^@

But it produces:
^A^@^@^@Z^A^@^@^@

on 32 bit machine or using -m32 on opteron.

I beleive this is libfortran bug or feature, but I still thing the files should
be readable across the platforms, or there should be some compile time option
for this. I hope this is not against some stupid standard :-(
