Updated to gfortran from Mac HPC Site (August 2008)
I noticed that there was a new version of gfortran available from the Mac HPC site, though it has probably been available for a while now. I was looking at the Intel FORTRAN compilers and at $600 each, you have to have something significant to use it on in my book. There's nothing wrong with the gfortran compiler, and while I'm not solving weather problems or simulating nuclear explosions, it's still cranking out answers for me that took machines a few years ago a long time to answer. That's not bad.
I still remember very fondly the days in grad school writing FORTRAN code for the Cyber 205, Gould NP1, and the Sun 3/60... fun days indeed.
