Using CRAY pointers with libc malloc/free is e.g. a common way to get
dynamic memory in Fortran 77.

Yes, that is why NumPy has f2py :-)
- Explicit shape and assumed size arrays can be passed as a pointer to
the first element. We can use numpy.f2py, ctypes or Cython for this
purpose. I usually put all my Fortran 95 code in modules, and expose
them to Python via driver subroutines.
- Fortran 2003 has bindings for ISO C that makes this portable. fwrap
automates this process, so we don't have to write all the boilerplate
code by hand. It is still immature though, e.g. no sujpport for modules
last time I checked.
