I tried FC=f90, which did solve above problem linking ftest in src/fortran.
However ftest produced following:

No.

Yes.  In fact even using f90, linking still fails for nf_test in similar way
to that in which ftest link failed before.  The output is:

Thanks again for your help.  We seem to be making some progress, even
if rather slowly!
