[CMake] FORTRAN name mangling

[Thompson, KT]

Michael,

You should always test your toolchain first.  Compilers are often buggy or may not fully support a language feature.  But yes, requiring F2003 should address your concern.

So if I require Fortran 2003 for our fortran codes then this whole “fortran name-mangling” thing becomes a moot point, i.e. I do not have to actually worry about it at all for our project. Just have to keep the C header consistent with the FORTRAN functions, but that part is on our devs.
