I should have mentioned that I already tried this. I get an error from
the preprocessor:

cpp0: Invalid option -i8

This was why I tried to switch to the compaq compiler.

I wasn't sure if I could run it (gcc) without -i8 and still be free from
the restrictions associated with i4 (active orbitals, file size ...).

My thinking was that as most of the important stuff is in Fortran I
could probably get away with it.

Is this correct ?
