4 byte integers with gfortran

[belson17]

I have a large legacy code compiled for intel's ifort compiler, and I'm trying to compile it with gfortran. The original code saves unformatted files with 4-byte integers. I need to do the same with gfortran, but the only relevant compiler option I've seen is -fdefault-integer-8, not -4.

I'd like a way to do this through compiler options if possible, changing all the declarations from integer to integer*4 is a last resort.

Thanks!

The default is -4. If you are working on an app which has to work on 64-bit, then use the -8 option.
