When application code that use the modules (compiled into the library) is
compiled, the
compiler requires the .mod files.

I do know, however, if you are providing a library .mod files are NOT

Submodules (which I have never used) address the compilation cascade
problem, but I
think you're mistaken about the second part.  The way an array object, for
example, is implemented
(rank, bounds, strides, memory address, etc) will vary between compilers;
 you can't pass an array
created in code built by one compiler to a procedure built by another.
 You'd need some sort of Fortran ABI standard, which doesn't exist, for
this to work.
