OK this is what I had presumed to be a GCC-internal/private directory.

Hmm, ...

What I was referring to (and implicitly proposing) was GCC/gfortran to
be extended to have a "standard, system-wide, GCC-independent" *.mod
installation directory/*.mod-search path, similar to /usr/include for
cpp'ed sources (c/c++-headers).

But ... if, as you say, *.mod's are really are compiler-dependent, then
gcc-gfortran(f90) has a real problem.
