One other point that might save you a bit of time and frustration:

For larger  programs you might want to link with cf77 rather than cc.
In C you explicitly link against everything except libc.a.  In fortran
there is a rather large list of libraries that get linked automatically.  
If you link with cc you must specify the needed fortran libraries and get 
the order correct.  cf77 pulls in the needed fortran libraries implicitly.  
You merely add -lc after the other C libraries you specify.
