I don't know if it never worked in gfortran. Until a few days ago, the only
MinGW build of gfortran was a trunk version of 4.3.0. I haven't tested gfortran
4.2.1 or any other version yet.

The program opens a large number of file units, some of them actual files, and
one of them 'con'. I believe one of them is also 'nul'. These are defined at
one place in the program that you can change (similar to the code in the sample
program in the first comment), so that at compile time you can change the names
of the files. That's just the way the program is written, and not being the
author, I can't reasonably change it all around to use the default units
instead.
