It's gone, replaced with gfortran: A new Fortran front end has replaced the aging GNU Fortran 77 front end. The new front end supports Fortran 90 and Fortran 95. It may not yet be as stable as the old Fortran front end. http://gcc.gnu.org/gcc-4.0/changes.html If gfortran doesn't work for you, you'll need to go back to the gcc 3.4 series (currently 3.4.4) to get g77 back.
