I forgot: another possibility is to use gfortran instead of g77, but you
will have to recompile everything (you cannot really mix g77 and
gfortran code together), including BLAS/LAPACK. For FC6, I remember that
gfortran is the default ABI, so this is anyway the best choice, but I am
not sure for FC5.
