Most Fortran 90 features require dwarf-3.  You can do almost nothing
with types for Fortran arrays that need array descriptors.  For
modules, renaming of imported symbols is also not in dwarf-2 afaik.

But it really doesn't matter if the compiler does not produce this
debug information to begin with.
