I think if you're also using fortran compiler that support iso_c_binding (a fortran 2003 standard) that may also help ensuring the data types are the same. The latest gfortran supports this.

> Yes, it should be no problem. It is easiest when the representations of the data by your two compilers are the same (e.g., REAL == float, INTEGER == int). It may be easiest to use compilers from the same vendor / family for linkage purposes, but it probably isn't 100% necessary.
