that would be the immediate fix.

c) compile all sources using gfortran and drop g77. Linking libraries
against libg2c and libgfortran doesn't work, so we will need to rename
library packages when we start building them using gfortran (discussed
on fortran@gcc.gnu.org). I will file bug reports for those
packages. We should start using gfortran-4.2, after that is the
default gfortran compiler.
