In my experience, I never had this kind of problem. I just have to convert files between big/little endian with uswap (http://linux.die.net/man/1/uswap), but I never see, in my experience, a Fortran program writting data differently given the compilator.

Unfortunately., binary files are mandatory in the contex I work. I use a scientific code written in Fortran to compute fluid dynamics. Typically the simulation is run on supercalculator and generate giga and giga of datum, so we must use the binary format, which recquire less memory for the stockage.
Then, I like to post-trait the datum using Python and Gnuplot.py.
That's why I'm looking for a performantant, easy and 'standard' way to read binary Fortran files. (I think many people have the same need).
