[Cython] Fortran types in C

ISO Fortran 2003 has standard bindings to ISO C. Most Fortran compilers
support them, including gfortran. These C bindings make C callable from
Fortran, but they also make Fortran callable from C in a standardized and
portable way.

The short receipe is: you don't declare any Fortran types in C. You
declare your Fortran functions with C types. This even includes
pass-by-value calling convention. Then the Fortran compiler will do the
correct conversion.

Take a look at the array-descriptor library of Chasm.
