Ahah!  I went on this:

  -h <filename>    Write signatures of the fortran routines to file <filename>
                   and exit. You can then edit <filename> and use it
                   of <fortran files>.

[emphasis mine].  The instead there led me to think that I should NOT
list the fortran files.  Should that docstring be fixed, or am I just
misreading something?

And do you have any ideas on why the f2py_options in setup.py don't
correctly pass the --fcompiler flag down to f2py?  It does work if one
calls setup.py via

./setup.py config_fc --fcompiler=gnu95 build_ext --inplace

but it seems it would be good to be able to set all f2py options
inside the setup.py file (without resorting to sys.argv hacks).  Or
does this go against the grain of numpy.distutils?
