Upgraded to the January 2010 gfortran
Since I was doing some simulations yesterday, I decided to have a look-see at the state of gfortran at the HPC on Mac OS X web site. Sure enough, they had an update. I have been running the September 2009 version, and they are up to the January 2010 release. Good enough reason to get busy installing!
I then ran through all my FORTRAN code again, and it even caught a few 'column 72' errors that had slipped by. Interestingly enough, MacVim pointed these out with a yellow background highlight! Very neat. I did the easy fix and the warnings went away.
I do so enjoy FORTRAN. It's just plain fun to work with.
