I am not sure this is safe. At least I was warned when I used a similar shortcut some years ago when I had some trouble with g77 on MS-DOS (djgpp port). g77 used to apply f2c libraries in her childhood, but has grown independent since then and so the libraries forked (libf2c and libf2g). I think that there *may* be a danger of strange behaviour in some other places if we just resort to drop in f2c-libraries in g77, and at worst, this behaviour remains undetected. 

Not all Fortran fails. For instance, MASS (or all of VR_*) loads (and runs) beautifully, although it uses many Fortran routines.

cheers, Jari Oksanen
