Disclaimer: I am not a fortran developer, I know nothing about fortran,
only about packaging software compiled with fortran compiler and related
For atlas, it is hardly a problem I think, because atlas is a C library.
There is an option to compiler a fortran wrapper, but that's it. The
problem is more with blas and lapack (which tests are failing with
gfortran but not with g77. Note that for Lapack, a number of tests fail
with both compilers).

By default, I meant from an ABI point of view: see for example the
following link: http://gcc.gnu.org/ml/fortran/2007-01/msg00611.html.
Calling convention default are different in g77 and gfortran, and as
such, if you don't use the default ABI, you become incompatible with
