Without using the -ff2c options, that causes bugs in Octave when using ATLAS. 
I tried to compile Debian's ATLAS package with gfortran, but the testsuite 
fails.

Now, I guess that using g77 would be the easiest option for both sides: we get 
a working package and you can easily mass-file bugs against packages using 
g77 later. Is that correct?

Is there a timeframe when this will happen?
