JSON-Fortran requires a modern Fortran compiler, so it needs to have that module (I think that's a Fortran 2003 feature).

@jacobwilliams It is not a Fortran standard issue at all, it is a platform issue. Not all platforms have ieee_arithmetic implemented at the moment. The latest upstream GCC does not have it for a number of platforms.
